There are at least 160 moons in our solar system, but the Moon, or Luna, Selene, is our planet Earth's only natural satellite.

The Moon is a round rocky body about 3,476km in diameter. In comparison, the Earth is about 50 times bigger (12,756km in diameter). The Earth is also a lot more interesting, mainly because it has an atmosphere, which allowed life to evolve on the planet's surface.

If you peeled the Moon like an apple and stuck the bits onto the Earth, it would just cover Africa.

The Moon is about 400,000 km away from the Earth, and is stuck in an orbit around our planet, taking one mo(o)nth to go all the way around. If you could drive to the Moon in a fast racing car (say at 250 km/h) it would take two months of non-stop driving to get there.

Together, the Earth and Moon go around the Sun, our nearest star, once a year. The Sun lies about 150 million km away from us.

The Moon is often thought of as being lifeless and cold. This is only two-thirds correct. The Moon is, in fact, lifeless, cold, and hot. The Moon receives as much light from the Sun as the Earth, but without an atmosphere to regulate things, the daytime temperature soars to 130C and plummets to -170C at night.

The first human to set foot on the Moon was Neil Armstrong (on 21 July 1969). The last human to step off the Moon was Eugene Cernan (on 14 December 1972).

If you shrink the Earth to the size of your head, then the Moon is about the size of your eye, and orbits your head at a distance of six metres. The Sun would be 2.5 km away, a massively hot 20 metre diameter sphere of nuclear explosions.

The Moon by any other name would be equally bright
