An extrasolar moon, or exomoon, is a natural satellite that orbits an extrasolar planet or other extrasolar body. Although no extrasolar moons have yet been observed, it can be inferred from the empirical study of natural satellites in the Solar System that they are likely to be common elements of planetary systems. The majority of detected exoplanets are gas giants and in the Solar System, the gas giants have large collections of natural satellites (see Moons of Jupiter and Moons of Saturn). However, detecting them would be extremely difficult with current techniques.

Famous quotes containing the word moon:
“She is not terrified of
begonias or telegrams but
surely this nightgown girl,
this awesome flyer, has not seen
how the moon floats through her
and in between.”
—Anne Sexton (1928–1974)
