Question

which force keeps the planets from floating off into space? earths gravity the suns gravity the moons gravity milky ways gravity

Explanation:

Planets in our solar system orbit the Sun. The Sun's gravitational pull acts as a centripetal force, holding them in their orbital paths and preventing them from drifting into space. Earth's gravity only affects objects near Earth, the Moon's gravity has a limited local effect, and the Milky Way's gravity acts on the entire solar system as a whole but not to keep individual planets from floating away from the Sun.

Answer:

the Sun's gravity
