Extrasolar moon

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.^[1] Observations from missions like Kepler have found some planetary objects that might be exomoons, one of them includes Kepler-1625b I.
