How far can you see?

This moon is doomed. Mars, the red planet named for the Roman god of war, has two tiny moons, Phobos and Deimos, whose names are derived from the Greek for Fear and Panic.

Apollo 12 was the second mission to land humans on the Moon.

Does the Sun return to the same spot on the sky every day at the same time? No.

Have you ever seen a halo around the Moon?
