As Earth gets closer to the sun in part of its orbit, the force of gravity increases, thus increasing its velocity.

As Earth gets further from the sun in part of its orbit, the force of gravity increases, thus decreasing its velocity.

Earth's velocity changes as it spins.

Earth's velocity is affected greatly by solar winds.

all planets in our solar system revolve around the sun in the same direction

many celestial bodies rotate and revolve in the same directions as objects around them

galaxies are all moving away from each other due to the expansion of the universe

none of these are false

Moons orbit planets and planets orbit stars.

All planets in our solar system revolve around the sun in the same direction.

One Earth rotation is the length of an Earth day and is the reason we experience night and day. One Earth revolution around the sun is the length of a year.

Stars, planets, moons, and other objects in space orbit around each other due to dark matter.
