If you had a sphere of pure Iron-56 as wide as the sun, would it start burning like a star? Would it stay solid like a planet or would it do something else?

 Iron-56 is the definition of death for stars.

It’s like cyanide.

Once Iron-56 forms in stars, there’s no escape from certain death for them.

Typically, when you have a body as massive as the Sun, it collapses under its own weight, which heats its core and triggers nuclear fusion.

Under this tremendous pressure and temperature, the light elements start undergoing nuclear fusion and release enormous energy, which balances out the stellar collapse due to gravity and keeps the stars alive for a long time.

Well, at least that’s what happens when the body is made up of lighter elements like Hydrogen.

Iron-56 is Different

When Iron-56 fuses, it does not release energy. In fact, Iron-56 consumes energy to undergo nuclear fusion.

So, if you happen to create a huge stellar-sized body made of Iron-56, you have a big problem on your hands.

As it collapses under its own gravitational force, it cannot trigger a net energy-producing nuclear fusion for the life of it.

In other words, there’s no fuel to feed the engine at the core, even under its tremendous heat and pressure.

Just unyielding, certain death for the doomed Iron-56 star.

There is only two potential futures for our pet project now.

What Happens to Our Iron-56 Star?

The Sun has an average density of 1,408 kg/m³.

Even if we could somehow create a body made of Iron-56 “as wide as the Sun,” with uniform density, it would be approximately 5.6 times more massive.

When this massive body collapses under its own mass, it rapidly crushes every Iron-56 atom at the core. Electrons are pushed right into the nucleus of the atom,. Electrons and protons are crushed together and turned into neutrons.

A neutron star core is formed.

The energy from this transformation is released as kinetic energy that ripples across the entirety of the star’s interior.

The outer layers of our Iron-56 star are flung away into space, creating conditions similar to a supernova. What’s left behind is a neutron star with mass less than 2.3 solar masses.

However, on the off chance that the Iron-56 star we created does not have a uniform density, like it’s usually the case with planets and stars, as they tend to have a denser core, we’ll have an initial body that’s much more massive than just 5.6 solar masses.

When it collapses, the core alone could be more massive than 2.3 solar masses.

Well, guess what! A heavier than 2.3 solar masses core is staring at a single fate when it cannot perform nuclear fusion – a black hole!

And here’s the kicker: the sheer implosion would be so fast and complete that it would all be over in a matter of seconds.

Edit 1: The original version presented a single potential future. It has been corrected to two, depending on the mass of the body.

What would happen if a star 'touched' the solar system?

 

You wake up one morning, turn on the TV, and there is a sci-fi film about people panicking because our Solar System is about to be hit by another star. You hate such movies. You change channels, but surprisingly, there is the same story on other channels as well. It was not fiction at all. It was happening for real. A hypervelocity brown dwarf star about 13 times as massive as Jupiter, approaching at 4% of the speed of light, has only been noticed because such suns can be even at room temperature, and some don't shine much. It will touch our Sun as it will fly by our system in just a few hours.

This violent side collision would shave off a bit of our star. The immense amounts of powerfully ejected matter would blast through the whole Solar System and furiously crash into planets. If the doomed Earth survived at all, it would be ruthlessly resurfaced and changed into liquid magma in which our ruined cities would submerge. The surface would cool again only millions of years later. This would spell the end of our forsaken civilization and possibly even life on our planet. Counterintuitively, the reduction of the mass of our Sun would extend its life by hundreds of millions to billions of years and make the orbits of the surviving planets expand because of the lower gravitational grip on them. Less massive stars have longer lifespans significantly. The blasted matter would eventually settle into a disk in which new planets could form as new neighbors to the ones that survived this surreal armageddon.

And surreal it would be, literally, because it would not be likely to happen. The distances between stars in our part of the galaxy are just too vast. A star touching another star system in our location in the Universe means something else. It would just be an approach that might disrupt some asteroids in the Oort Cloud, resulting in some comet strikes on planets. Infinitely rarely, stars can approach each other somewhat closer. This can result in their planetary systems becoming unstable. Some worlds can change orbits, collide, fall into one of the stars and be destroyed, or some can be ejected and become rogue planets.

Stars occasionally collide directly in some dense clusters of stars and in the galaxy's central bulge. There is evidence of it because blue straggler stars have been detected in these locations. They formed via the collisions of stars. They are brighter, and their light is bluer than similarly massive stars that formed in a usual way. If suns collide at a very high speed, they can dissipate and become gas clouds. If they hit each other at an angle, they might start revolving around their common center of mass, the barycenter, ever closer until even billions of years later when they might collide. Such impacts can expel massive amounts of matter, forming a protoplanetary disk where new worlds can coalesce.

Why do some star systems have Jupiters that are super close to their suns, and why is our solar system different?

 

The funny thing is that our Solar System may in fact be quite average. The problem lies in being able to detect exoplanets at all. The larger and closer a planet is to a star the more likely we are to detect either the wobble of the parent star or change in brightness from the transiting planet. In both cases, being close to the star makes it more likely to be detected since the orbital period is short. It also helps if the planet is large and massive such as gas giants which are really the only ones that can affect a detectable wobble. The larger surface area of gas giants also makes the change in brightness caused by a transit large enough to be detected. Our Sun’s planets, in contrast, would be hard to detect. Jupiter’s period is about 12 years which means it would take that long to see a wooble cause by it and be able cancel out the Sun’s proper motion. It is also how long you would need to wait (assuming the observer’s line of sight aligns with our ecliptic plane) for anyone to notice a repeat of the begining or end of Jupiter’s transit. Saturn would be even worse for detecting a transit since its period is 29 yrs. A Uranus or Neptune transit may be seen only once in a lifetime if at all within either period of 84 yrs and 165 yrs. Smaller planets, because of their proximity to the Sun like Mercury, Venus, Earth, and Mars would transit more often but would be harder to detect. So, it should not be surprising that the vast mayority of the exoplanets detected are Jupiter size.

There is a size comparison of all the planets to the Sun (notice the four large gas giants) in the simulated image below:

What is the largest star in space?

 We will never know the largest star in space. We can only tell you what is the largest star discovered to this date. The Universe is simply too vast to say that what “WE” found is the largest star in space.

That is Stephenson 2–18

Stephenson 2-18 (St2-18) is a red supergiant located in the constellation Scutum. Also catalogued as Stephenson 2-DFK 1 and RSGC2-18, it is the current record holder for the largest star known, with a size 2,150 times that of the Sun.

How big is Stephenson 2-18, among the largest stars in the known universe? It would take earth's fastest jet over 500 years to travel around. It would take almost 9 hours at the speed of light. Its circumference equals the orbit of Saturn.

The star is located at a distance of 18,900 light years from Earth. It is a member of the open cluster Stephenson 2.

So, as our telescopic technology or any revolutionary technology, let us pear deeper into space this we will find out that there are stars even bigger than Stephenson 2–18. It's just a matter of time and innovation.

Sun or Suryanarayana

Sun is the emperor of remaining ashtagrahas( eight planets).He is known as Suryanarayana, meaning visible form of lord Vishnu.He is the creator,sustainer and destroyer of life on earth.Therefore he is the embodiment of thrimurthis- Brahma ,Vishnu maheshwara — in this visible world.Aditya( another name of sun which means son of aditi) is the source of light for the 5 nakshatra graha( star like planets- mercury,Mars,Jupiter,Saturn and Venus) and Chandra( moon).Thus he is the primary luminary.Owing to all these qualities,sun is the best planet to represent soul.Therefore is the only planet, which is considered as a papa graha(natural malefic) as well as Satvika(most good natured).

According to jaimini system sun is the permanent Atmakaraka.Soul is a part of paramatma,like a drop from an ocean.The drop must have all the qualities of water from ocean ,like wise sun represents soul by its property of light.

Simha(Leo) is the own house of sun.Simha rashi represents a lion which is the best sign to present sun the emperor.He is usually depicted as riding a chariot ridden by 7 horses representing 7 components of white light.It is controlled by Aruna(son of vinatha, mother of garuda- thus Aruna is a brother of garuda-)

Sun gets exalted in the sign of Mesha(Aries) — more specifically in 10th degree of Mesha.Sun covers entire elliptical in 365 days.Thus covers 1° in one day. He is exalted in 10th day of the month of Mesha(falling on 24/25 of April every year).This day is very important regarding the commencement of agriculture in almost whole of south asia(India,Nepal, Bhutan,and shri lanka) along with some parts of Tibet, Myanmar,southwest china,northern Thailand and Laos.

Sun gets debilitated in the sign of Thula( Libra) ,more exactly 10 th degree of Libra.

The duration of sun in a sign is 30/31 days and it represents a month.In Indian solar calendar,each month is named according to the sign in which sun is posited.The month of

Mesha is from : 14/15 of April to 14/15 of may

Vrishabha: mid May to june

Mithuna: mid June to july

Karkataka: mid July to august

Simha:mid August to september

Kanya:mid September to october

Thula: mid October to mid November

Vrishchika:mid November to mid December

Dhanu: mid December to january

Makara: mid January to february

Kumbha:mid February to mid march

Meena: mid March to mid April.

Thus completing a full year.

In a chart sun represents ones own soul, his father, his image in the world, pride and so on.Sun is with his maximum power in terms of Dig Bala(directional strength) when he is posited in 10 th house of chart.It represents mid noon in real world.

From second half of 1st house to 1st half of 7 th house in a horoscope indicates inner (invisible)qualities of native,that are known to native or his close relatives and friends.The other half, from 2nd half of 7th house to 1st half of 1 St house indicates outer qualities (or known or visible qualities) of the native.When sun gets posited in 10 th house,it is present at the centre of visible houses,thus iluminating all aspects in tis area.Such a native will be well known in his circle.He is likely to serve the government.But if the rashi becomes too bad or too good, it may cause arrogance in the native.Sun is devoid of digbala in 4 th house,that is midnight.In this position,it is found that mother of such native will do the work of his father and father will do the work of mother.Such a native will be working in government,since sun aspects the 10 th house, but in a unknown manner towards public,but his role will be very important.

Sun has a property that is not found in any other planet.That is ,whenever any other planet (except rahu and ketu)comes too near to him, their power will get diminished in the light of sun.This is called as astha planet( combust)This repeatedly occurs with mercury and Venus.

Sun has friendly relationship with Jupiter,moon ,mars and mercury is considered as equivalent.Venus and Saturn are enemical to sun.Rahu and ketu are worst enemies of sun.Saturn ,even though son of Surya(sun) considers sun as enemy ,because of some incidents that occured to his mother, Cchaya Devi.Sun has another son- Yama, and a daughter- Yamuna.The earthly embodiment of Yamuna is the river Yamuna.She is most auspicious near vrindavana and it is considered to be very good to take a dip in Yamuna, as a solution to pacify sun in chart.

Is Shah Rukh Khan the biggest self-made star in Bollywood history?

 Not at all!!!! Dharmendra is the biggest self-made star in Bollywood.

Dharmendra was born in Nasrali, a village in Ludhiana district. He did his education from a government school. He participated in a talent hunt organised by Filmfare magazine and went to Mumbai as he was promised for a film role for winning the contest. The film was never made.

He had no money and knows no one in Mumbai. He gave several auditions and then got his first break in 1960 in film “Dil Bhi Tera Hum Bhi Tere”. He got only 51/- Rs. as payment for his first film.

The film was not successful and his struggle continued. After years he got his first hit film Bandini and then his journey to stardom begin.

Dharmendra never got any Filmfare award. He never was supported by any big camp. He worked and worked and worked.. In his career of almost 60 years he has done around 250 films.

How big can a star form?

 

The stars at the bottom are the biggest currently known stars. 1 AU is the distance between the Sun and the Earth.

The biggest stars that could ever have formed are thought to have existed billions of years ago, just after the Big Bang. They were enormous, even more than 1000 times as massive as our Sun. In comparison, the biggest star known from our time is BAT99‑98, which is only 226 times as massive as our Sun.

These hypothetical stars were called quasi-stars or black hole stars because they had a black hole in the middle of them.

Because of their size, they are thought only to have existed for about 7 million years. They were so huge that they might have been progenitors of the supermassive black holes at the center of modern galaxies. They weren’t powered by nuclear fusion like regular stars; instead, their brightness came from the material falling into the black hole in their core. Because they were so massive when the black hole formed inside them, they didn’t explode like a supernova. Surrounding layers of the star absorbed the explosion and the newly formed black hole started consuming the star from within.

In our time, such huge stars cannot form anymore—there is too much contamination from elements heavier than hydrogen and helium. There were no such heavy elements in the first generation of stars just after the Big Bang. They appeared when the first stars formed, produced them via nuclear fusion, and spread them in supernovas.

These monsters had temperatures of about 10,000 K, and they might have been more than 7000 times as big as our Sun or 66 times as wide as the distance between the Sun and the Earth. During their short lives, they are thought to have cooled to temperatures of about 4,000 K, which caused them to dissipate and die, leaving behind just the black hole.

What is a hypervelocity star?

 

The mysterious hypervelocity stars jet through space at mind-bogging speeds. The fastest known one is S5-HVS1, and it travels at 0.58% of the speed of light. This is how they can achieve such incredible velocities.

• Stars, which survived supernova explosions of their binary partners, can be accelerated to up to 0.375% of the speed of light.
• Our galaxy has about 59 known satellite galaxies. Some pierce the disk of its spiral if they are close enough and their orbit is vertical. During this process, they accelerate some stars to escape velocity speeds. Some are only accelerated to speeds giving them elongated orbits, or they can become halo stars that are gravitationally bound to our galaxy but are not located within the disk of the spiral.
• Similarly, stars can acquire escape velocity speeds from our galaxy by approaching each other too closely. It almost never happens in the outer regions of the galaxy where we are located but is more frequent in the central bulge of our galaxy and in some dense clusters of stars, where distances between suns are much shorter.
• Between 8 and 11 billion years ago, our galaxy merged with the Gaia-Enceladus galaxy, which increased its number of stars by about 50 billion to the 200–400 hundred billion, it now contains. It caused the ejection of many systems from the merged galaxy. In 4.5 billion years, the Milky Way will collide and merge with the Andromeda Galaxy. It will eject about 12% of systems from the outer regions of the spiral where we are located. They will acquire escape velocity speeds.
• By far, the fastest stars acquired their velocities when they were a part of a multi-star system that encountered massive black holes, especially the supermassive black holes in the centers of galaxies. The ones that are freed from their system via this process can acquire up to an incredible one-third of the speed of light, but most would be accelerated to much more modest velocities.

Another type of fast star orbits massive, and especially supermassive black holes in the center of galaxies. The fastest known one, S2, orbits the supermassive black hole of our Milky Way Galaxy at an eye-popping 16% of the speed of light. Likewise, some binary stars orbit the common center of mass between the two, the barycenter, at very high speeds.

Is the Sun more powerful than other stars in our Galaxy?

 No, our Sun is an average star being.

The largest would be UY-Scuti.

The smallest wold be EBLM J0555-57Ab, a Saturn sized star, but size dosent add to power.

The opposit end of the question, the weaker stars being the M-Clas rad and brown dwarfs, (Im adding jupiter as a planet that thinks it's a radio rich M-Class star, but jupiter being just a little stronger than some,

Jupiters Jovian system..

The strongest by far would be the tiny class of Neuteon stars, non more powerfull than the Magnetars, some of the most powerfull stars we will ever find.

Can be stronger than some black holes.
