Betelgeuse is 425 light years away and is 60,000 times brighter than our star the Sun (Sol). It is so big that if you replaced the Sun with Betelgeuse, Betelgeuse would fill our solar system to out past the orbit of Jupiter | added by isaac |
Jupiter is bigger than all the other planets combined | added by ray |
The Sun is only an average size for a star but still accounts for 98% of the total matter in our solar system | added by Jack |
It’s believed by scientists that we can only see approximately 5% of the matter that is in the universe. The rest of the matter is made up of matter that’s invisible, which is known as Dark Matter, and a very mysterious energy form called Dark Energy. | added by ChrisM |
Every year, the Moon is moving away from Earth by 3.8 centimeters | added by danny |
Every year the sun evaporates 100,000 cubic miles of water from Earth (that weighs 400 trillion tonnes!) | added by susana |
