Harry Coumnas is very interested in learning whether life exists on the natural satellites of the solar system. The gravitational attraction between the satellite and the object it is circling keeps the different natural satellites in our solar system in orbit. The Moon, Europa, Ganymede, Callisto, Phobos, Ceres, Halley's Comet, Earth, Jupiter, and Venus are examples of natural satellites.

It is generally accepted that the same collapsing region of the protoplanetary disk that gave origin to the planet's main created these naturally occurring satellites that orbit quite near to it. Natural satellites are expected to significantly outnumber planets, according to Harry's study and investigations. Factors pertaining to habitability are thought to be comparable to those of planets.

Enceladus, Saturn's sixth-largest moon, is the best candidate for extraterrestrial life, according to Harry Coumnas, who goes on to discuss his beliefs regarding the possibility of life. An icy moon with life-sustaining components like organic molecules, water, etc., makes it appear to be habitable.
