Orbiting cannon balls

Lets say we are far away from any stars. I get 2 cannon balls from the spacecraft and put them next to each other. Will they orbit each other or remain in the same exact spot?




Lenovo g500s Core I3 2.4ghz dual core, 4GB ram, Intel HD 4000 graphics :(

They won't remain on the same spot because of their gravity. They will slowly fall towards each other. If you put them a metre apart, they'll collide after about 4-5 hours. If you gave them a tiny push, enough to miss each other by this time, they'd end up orbiting each other instead as if they were a tiny binary star. Universe Sandbox actually has a very amusing pre-created simulation of a tiny little solar system with a bowling ball as the sun and various other sportsballs, dice, and a teapot as planets.

The cannon balls may go towards you.




Math is the "programming" language of the universe.

^ because you have more gravity than them, yes, if you're willing to wait there for hours waiting.




Living among the stars, I find my way. I grow in strength through knowledge of the space I occupy, until I become the ruler of my own interstellar empire of sorts. Though The world was made for the day, I was made for the night, and thus, the universe itself is within my destiny.
