The Circumstellar Habitable Zone:-
The Circumstellar Habitable Zone is the range of orbits around a star within which a planet can hold liquid water given enough atmospheric pressure.
So here is the list of some Potentially Habitable Exoplanets:-
1.) Teegarden’s Star b.
This is an exoplanet orbiting the Teegarden’s Star, about 12 light years away from our Solar System. It is the fourth closest potentially habitable exoplanet. This is the innermost known planet orbiting the Teegarden’s Star with an orbital period of just 4.91 days. This planet is likely to be rocky. It may even have an ocean of water on its surface. It orbits within the habitable zone of its host star. Teegarden’s star is inactive and quiet, increasing the chances that Teegarden’s Star b may be habitable.
2.) TRAPPIST-1d
TRAPPIST-1d was detected with the transit method. The density of TRAPPIST-1d indicates a manily rocky composition. TRAPPIST-1d is a closely orbiting planet which takes only 4.05 days (about 97 hours) to complete one orbit. This exoplanet is one of the most Earth-like planets. It does not have a hydrogen or helium-based atmosphere, which makes largest planets uninhabitable. Its host star TRAPPIST-1 is some 40 light years away.
3.) Kepler-1649c
This is an Earth-sized exoplanet, likely rocky. It was discovered by the Kepler spacecraft on 15 April 2020 by the transit method. It takes about 19.53 days in orbiting its host star Kepler-1649. It may be tidally locked. As of 2021, no solar flare-ups have yet been observed from its host star. It receives 75% of the light from its host star that the Earth receives from the Sun.
4.) Proxima Centauri b
This planet orbits in the habitable zone of its host star Proxima Centauri, the closest star to the Sun. Proxima Centauri b is the closest exoplanet to the Earth. Proxima Centauri itself may have been captured by Alpha Centauri and thus is not necessarily of the same age as the Alpha Centauri. Proxima Centauri b is likely to be tidally locked to its host star.
