Which of the following is the primary reason we experience night and day on Earth?
Stars, planets, moons, and other objects in space orbit around each other due to gravity. This type of motion is called revolution. Many objects in space also spin in place. This motion is called rotation.
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. Other planets have different lengths of days and years because they rotate and revolve at different speeds.
All planets in our solar system revolve around the sun in the same direction. Most of them (with the exception of uranus and venus) rotate in the same direction as well.About half of the galaxies in the universe rotate clockwise, and the other half rotate counter clockwise. Scientists think this may be because of the way our universe began.
