"The moon of a bright silver, which dazzles by its shining, illumines a world which surely is no longer ours; for it resembles in nothing what may be seen in other lands." --Pierre Loti
The Moon (IPA: /mun/) or Luna is Earth's only known natural satellite and the fifth largest satellite (after Ganymede, Titan, Callisto, and Io in that order) in the Solar System. The Moon is also extremely dense and is the second densest moon after Io. The Moon (other than the Earth) is the only natural extraterrestial body on which humans have set foot apon. There is evidence of volcanic activity in The Moon's past, though it is unlikely vulcanism still takes place today or has been active recently.
