Our Moon has been a source of wonder to humanity, since time began. It is our nearest neighbour in the Universe, and the only other place in the Universe, to have been visited by humans.
Average diameter: 3,474 kilometres, or 2,159 miles
Mean distance from Earth: 385,000 kilometres, or 239,000 miles
Tilt: 1.5 degrees
Rotation period: 27.32 Earth days
Orbital Period: 27.32 Earth days
When the full Moon occurs at the same time that the Moon is closest to the Earth (perigee), the event is referred to as a Super Moon (left). When the full Moon occurs at the same time that the Moon is furthest from the Earth (apogee), the event is referred to as a Micro Moon (right). Super Moon events can appear more than 10% larger and about 30% brighter than Micro Moon events.
The craters near the Moon's poles are in perpetual darkness.

The Apollo Program refers to a series of missions undertaken by NASA in the 1960s and 1970s. The primary objective was to land a man on the Moon, and return him safely to the Earth. Successful lunar landings occurred a total of six times, landing 12 men on the Moon and returning them all safely to the Earth.
