An exoplanet or extrasolar planet is a planet outside our solar system that orbits a star. This is a list of habitable exoplanets and possible exoplanets. We are introducing you top 10 potentially habitable exoplanets, that is based on estimates of habitability by the habitable exoplanets catalog (HEC), and data from the NASA Exoplanet Archive. The HEC is maintained by the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo.
Kepler-62e is a super-Earth exoplanet (extrasolar planet) discovered orbiting within the habitable zone of Kepler-62. Kepler-62e is located about 1,200 light-years (370 pc) from Earth in the constellation of Lyra. The exoplanet was found using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured. Kepler-62e may be a terrestrial or ocean-covered planet; it lies in the inner part of its host star’s habitable zone. Kepler-62e orbits its host star every 122 days and is roughly 60 percent larger (in diameter) than Earth.
Kepler-62f is a super-Earth habitable exoplanet orbiting within the habitable zone of the star Kepler-62. It is located about 1,200 light-years km from Earth in the constellation of Lyra. In astronomy and astrobiology, the circumstellar habitable zone is the region around a star where a planet with enough atmospheric pressure can maintain liquid water on its surface.
Kepler-186f is one of the habitable exoplanets orbiting the red dwarf Kepler-186, about 550 light-years from the Earth. It is the first planet with a radius similar to Earth’s to be discovered in the habitable zone of another star. NASA’s Kepler spacecraft discovered it using the transit method, along with four additional planets orbiting much closer to the star. Kepler–186f orbits its star with about 4% of the Sun’s luminosity and an orbital radius of about 0.40 times that of Earth’s. The habitable zone for this system is estimated to extend over distances receiving from 88% to 25% of Earth’s illumination.
Kepler-296e is a confirmed Earth-sized exoplanet orbiting within the habitable zone of Kepler-296. The planet was discovered by NASA’s Kepler spacecraft using the transit method. NASA announced the discovery of the exoplanet on 26 February 2014. The planet was announced as being located within the habitable zone of Kepler-296, a region where liquid water could exist on the surface of the planet.
Kepler-296f is one of the confirmed habitable exoplanets. The planet was discovered by NASA’s Kepler spacecraft using the transit method. The planet is located within the habitable zone of Kepler-296, a region where liquid water could exist on the surface of the planet.
Kepler-438b is a confirmed near-Earth-sized habitable exoplanet, likely rocky, orbiting on the inner edge of the habitable zone of the red dwarf as it receives 1.4 times our solar flux. Kepler-438, about 470 light-years from Earth in the constellation. Kepler-438b is approximately 470 light years from Earth. The planet was announced as orbiting within the habitable zone of Kepler-438.
Kepler-440b is a confirmed super-Earth exoplanet orbiting within the habitable zone of Kepler-440, about 850 light-years from Earth. Kepler-440b is a super-Earth with a radius 1.86 times that of Earth. The planet orbits Kepler-440 once every 101.1 days. NASA announced the confirmation of the exoplanet on 6 January 2015.
Kepler-442b is a confirmed near-Earth-sized exoplanet, likely rocky, orbiting within the habitable zone of the K-type main-sequence star Kepler-442, about 1,120 light-years from Earth. K-type main-sequence stars are smaller than the Sun and live longer, remaining on the main sequence 15 to 30 billion years compared to the Sun’s estimated 10 billion.
The average distance from Kepler-22b to its host star Kepler-22. It is about 15% less than the distance from Earth to the Sun but the luminosity of Kepler-22 is about 25% less than that of the Sun. This combination of a shorter average distance from the star and a lower stellar luminosity are consistent with a enough surface temperature at that distance. If it is assumed that the surface is not subject to extreme greenhouse heating.
- Wolf 1061c
Wolf 1061c or WL 1061c is an exoplanet orbiting within the habitable zone of the red dwarf star Wolf 1061 in the constellation Ophiuchus, about 13.8 light years from Earth, making it the fifth closest known. It is the second planet in order from its host star in a triple planetary system, and has an orbital period of 17.9 days. Wolf 1061c is classified as a super-Earth exoplanet.
