An extrasolar moon, or exomoon, is a moon, or natural satellite, of an exoplanet, a planet around another star than our sun.
Exomoons are difficult to find and confirm. Observations from missions like Kepler have found some planetary objects that might be exomoons, one of them includes Kepler-1625b I.
