Exomoon

<p>An exomoon or extrasolar moon is a <a href="/facts/Natural_satellite/AE4KQKbq">natural satellite</a> that orbits an <a href="/facts/Exoplanet/zjfmqfUf">exoplanet</a> or other non-stellar <a href="/facts/Astronomical_object/BCHLa0Q2">extrasolar body</a>.
</p><p>Exomoons are difficult to detect and confirm using current techniques, and to date there have been no confirmed exomoon detections. However, observations from missions such as <a href="/facts/Kepler_(spacecraft)/E485cUts">Kepler</a> have observed a number of candidates. Two potential exomoons that may orbit <a href="/facts/Rogue_planet/3t9nlDVa">rogue planets</a> have also been detected by <a href="/facts/Microlensing/JL0fXQRC">microlensing</a>. In September 2019, astronomers reported that the observed dimmings of <a href="/facts/Tabby%2527s_Star/AgbWCgam">Tabby's Star</a> may have been produced by fragments resulting from the <a href="/facts/Disrupted_planet/qKCyt2KB">disruption</a> of an <a href="/facts/Tidally_detached_exomoon/ukoKIPk6">orphaned exomoon</a>. Some exomoons may be potential <a href="/facts/Natural_satellite_habitability/Sw3dsnHd">habitats for extraterrestrial life</a>.
