Across
- 1. - An imaginary line that a planet, moon, or sun spins or rotates on.
- 5. - The movement of a planet, moon, or sun on its axis.
- 7. -The amount of time it takes something to orbit something else once.
- 8. - The point in the orbit of a planet, asteroid, or comet at which it is furthest from the sun.
- 9. - The regular movement of planets, moons, or comets in space around other objects. Things are “in orbit” due to gravity. More massive things have more gravity.
- 10. - A unit in space equal to 94 million miles. The average distance from the Earth to the Sun.
- 11. - The point in the orbit of the Moon at which it is farthest from the Earth.
Down
- 2. - The unique orbit our Moon has around the Earth. It takes as long for the Moon to rotate on its axis once as it does to orbit the Earth. The result is that it appears the Moon never rotates!
- 3. - The point in the orbit of the Moon at which it is closest to the Earth. This is when we see Supermoons!
- 4. - The time it takes for a body to rotate once.
- 6. - The point in the orbit of a planet, asteroid, or comet at which it is closest to the sun.
