Not only in space - gravity is universal. The force of gravity is affected by the distance, and by the masses involved.
gravity is something that can affect the planets.
Air pollution or fog
no donot affect.
The simplest and best answer to that question is: -- Without gravity, there would be no orbits. -- Once you completely understand gravity, you can figure out everything there is to know about orbits, because it all comes from the behavior of gravity.
oxygen and gravity
Masses and distances
-- the product of the two masses involved -- the distance between their centers of mass
Mass, distance.
