Various ways. Gravity of stars act on planets and cause them to rotate around them, as well as asteroids that get caught in gravity fields and fall to the plant's surface.

it keeps us on Earth and in space, it holds everything even the milky way(not the chocolate bar , our Galaxy!)

Exactly, that is what a galaxy is.
I assume you mean the sombrero galaxy. It is a galaxy, hence it has mass, hence it has gravity. If you mean a "sombrero" as in hat, it also has mass and therefore gravity. The gravity, in each case, can be calculated via the gravitational formula.
