ShareThe Moon is Earth's only natural satellite.
The average distance from the Earth to the Moon is 384,399 kilometres (238,854 mi), which is about 30 times the diameter of the Earth.
At this distance, it takes sunlight reflected from the lunar surface approximately 1.3 seconds to reach Earth.
The Moon's diameter is 3,474 kilometres (2,159 mi), which is about 3.7 times smaller than the Earth, making it the Solar System's fifth largest moon, both by diameter and mass, ranking behind Ganymede, Titan, Callisto, and Io.
