05 The Moon

Earth’s only satellite, the moon is a rocky, solid body covered with craters. It has no atmosphere, so it cannot sustain life.

NAMING

Our moon’s name is derived from the Old English mona. Our moon is Earth’s only satellite. Other moons in our solar system have different names to avoid confusion.

FUN FACTS

The Earth and moon’s gravities pull on each other causing a tidal lock — the reason for the moon always facing the same side to the Earth.

Because our moon has no atmosphere, other space objects hit the surface without burning up first. The surface does not change, so craters and astronauts’ footprints remain on its surface.
