Buoyancy
Nothing "floats in gravity." Floating in a result of the buoyancy force provided by a fluid. Balloons float because of the buoyancy force from air. Boats float because of the buoyancy force from water. Objects that appear to float in space are usually in orbit, which is actually a state of freefall.
gravity?
The buoyant force on a floating object is equal to the object's weight out of water.
If it's floating, then the buoyant force on it must be 30 pounds upward.

Buoyancy
The force of the Sun's gravity keeps them in their orbits.
The force that keep's us (or you) is the gravity.
what keeps the moon from flying off into outer space
Gravitational Force
Gravity keeps trees from floating about.
The same gravitational force that keeps you from floating into space.
May the Force be with you! My daughter is in the Air Force. If the window sticks, do not try to force it open. The force of gravity keeps you from floating off the planet. You teacher will force you to do your homework.
