Universe is very, very, very big. In fact, our size is insignificant at a larger scale. Lets take a look.
The equatorial circumferance of Earth is 40,075 kilometres. We all know that we are extremely small on our own planet.
To know how small we are in the universe, let us start from our planet, and slowly go farther and farther away from it. Lets begin our journey.
This is an image of Earth taken by ISS, from a distance of 408 KM away from Earth. At this scale, we begin to feel that we humans are really small compared to our giant planet.
Next, let us recede.
This is photo of our planet from the moon, taken by the Apollo 11 team from a distance of 384400 kilometres.
Lets go more far. You can see a small but bright dot in this picutre marked with an arrow. That dot is our planet Earth seen from Saturn, i.e, from a distance of 1,448,409,600 kilometers.
Now lets go more far from our planet- 6 billion kilometres away. That’s a distance beyond Pluto.
This is how the Earth looks from that distance.
That small dot which is circled is our entire planet. All of 7 billion humans, the huge buildings we built, and everything we see, from a distance of 6 billion kilometres. This is an image taken by Voyager 1.
6 billion KM is a very small distance at the scale of the entire universe. 6 Billion KM is not even close to distance of light year, and this is a picture taken from inside Solar System itself.
Distances in the universe are measured in light years. And 6 Billion Kilometres is nowhere near a light year which is more than 9 trillion kilometres.
If even just from the farthest edges of Solar System our Earth looks so small, just imagine, how small it would be in the entire universe!
Our Solar System with Sun and all other planets is a one of the 100 billion stars in the Milky Way….
….which is a part of the local group of galaxies,
…. and local group in turn is a part of the Virgo Superclustre which contains many other galactic clustres.
Which is a part of Pisces cetus supercluster complex, a galaxy filament-
Which is a part of the universe that contains all the galaxy filaments, super clustres, clustres of galaxies, galaxies, and star systems which contain planets.
THats how big the universe is. At the scale of the universe, we are so small, that we become insignificant.
Thats how small are we in this huge cosmos.
