SOI

The meaning of 'SOI' is Sphere Of Influence, commonly used in games like KSP, or in astronomy, or simply in any advanced space exploration game. The Sphere of Influence is the range that a planet, star, asteroid, black hole, and any object can affect with it's gravity. The sphere of influence is not a very used word, since it's a very technical word (that means only smart ass'es can use it) The SOI (sphere of influence) depends on the mass(weight in vacuum) of the object, that means, everything has gravity and a SOI, but you might be wondering 'why cant I attract things with my gravity?' Simple, your gravity is too low to be able to do that. Long explaination, I know, but hey, what else you expect of a word that belongs from astronomy? (Thanks to the moderators if they accept this, lol)
