This is a list of some of the exoplanets that are more likely to have a rocky composition and maintain surface liquid water. Potentially habitable.
And the list goes as the following:
Differently known as (KOI-7016.01) is an exoplanet orbiting the Sun-like star Kepler-452. It’s about 1,400 light-years (430 pc) from Earth in the constellation Cygnus.
This planet was found by NASA’s Kepler mission inside the habitable zone around a sun-like star. It’s the smallest planet to date discovered orbiting in the habitable zone. An area around a star where liquid water could roam on the surface of an orbiting planet. Kepler-452b is 60 percent larger in diameter than Earth. So, it’s considered a super-Earth-size planet. Some research suggests that planets the size of Kepler-452b have a good chance of being rocky.
Also known as KOI-4742.01, is an almost-Earth-sized exoplanet orbiting within the habitable zone. It’s 1,120 light-years from Earth in the constellation Lyra. The planet was discovered by NASA’s Kepler spacecraft. It’s likely a rocky planet with existence of liquid water.Also, the planet was found using the transit method
Kepler-442b is an exoplanet with a mass and radius bigger than that of Earth, but smaller than that of the ice giants Uranus and Neptune. It has an estimated temperature of −40 °C (−40 °F) and the surface gravity on Kepler-442b could be 30% stronger than that of Earth.
2. Gliese 667 Cc
Also known as GJ 667Cc, HR 6426Cc, or HD 156384Cc, an exoplanet discovered on 2009, this kind of planet is a model of how an Earth-like planet could be. Gliese 667 Cc orbits within the habitable zone of the red dwarf star Gliese 667 C, which is a member of the Gliese 667 triple star system. It lies approximately 23.62 light-years from Earth in the constellation of Scorpius. It is heavier than Earth with a minimum mass of about 3.7 Earth masses. The estimated temperature of Gliese 667 Cc is thought to be 4.3 °C (39.6 °F).
1. Proxima Centauri b
Is an exoplanet differently known as (Alpha Centauri Cb or Proxima b). This exoplanet is the best candidate for habitability as it orbits in the habitable zone of the closest star to us, the red dwarf star Proxima Centauri. The exoplanet is at a distance from its star that allows temperatures mild enough for liquid water to pool on its surface. Is thought to have a rocky composition and a density equal to that of the Earth. The planet has an equilibrium temperature of −39 °C (−38 °F).
