How many Exomoons have been discovered?
Though exomoons are difficult to detect and confirm using current techniques, observations from missions such as Kepler have observed a number of candidates, including some that may be habitats for extraterrestrial life and one that may be a rogue planet. To date there are no confirmed exomoon detections.
What exoplanet is most habitable?
K2-18b may be the most habitable exoplanet ever found, but it is unlikely we’ll find life or even liquid water on its surface. At this point it just meets the most criteria on astronomers’ and astrobiologists’ laundry list of what’s necessary to support life.
Can exomoons support life?
Exomoons are the wild card in the ongoing chase for habitable worlds. Astronomers have discovered more than 1,900 exoplanets, a few of which might be friendly to life, but no moons circling these alien bodies have turned up as of yet.
