Kepler-11

Ok so the last physics quiz was pretty easy.

The main player was momentum, without any external force acting on a system, momentum is conserved. So if you manage to throw something to the right you go to the left, throw it up and you go down etc. This way you just need to throw anything you have in hand in the opposite direction you want to move.

Congratulations to antiquark2, shychemist and turningleavesorange who got it right, get ready for a harder quiz next time!
