Question

Discounting mountains, valleys, and other gross surface features, is there any place on Earth from which the Moon is not visible at all?
Asked by: Frank X. Guthrie

Answer

Just as the Sun is visible for 6 months out of every 12 at any point on the surface of the Earth, the moon can be seen from any point on Earth's surface at some time. The Moon is only 'invisible' to Earth in its 'New' phase when its lighted side faces away from us.
