Some of the best facts I have come across :
1. Our Solar System takes 255 million years to rotate around the milky way.The last time earth was in its current position , dinosaurs were just beginning to roam the earth.
Yes you read it right!!
2. Saturn’s Titin store hydrocarbons which is about 10 times larger than the earth’s petroleum and natural gas reserves combined.
3. As there is no earth's gravity in the space , the vertebrae starts expanding in our body which leads to the height gain.
This is the reason why astronauts usually complains that their height has been increased by few inches in the space. :)
4. Titin is the largest known Protein ever discovered. (C169723H270464N45688O52243S912). It has the largest IUPAC name at 18,891 letters. It takes approximately 3.5hrs to read it entirely.
