Kepler-22b (also known by its Kepler Object of Interest designation KOI-087.01) is an exoplanet orbiting within the habitable zone of the Sun-like star Kepler-22. It is located about 640 light-years (200 parsecs ) from Earth in the constellation of Cygnus .
Kepler-22 is a Sun-like star in the northern constellation of Cygnus, the swan, that is orbited by at least 1 planet found to be unequivocally within the star's habitable zone. It is located at the celestial coordinates : Right Ascension 19 h 16 m 52.2 s , Declination +47° 53′ 3.9″. [ 2 ]
K2-18b, also known as EPIC 201912552 b, is an exoplanet orbiting the red dwarf K2-18, located 124 light-years (38 pc) away from Earth. The planet is a sub-Neptune about 2.6 times the radius of Earth , with a 33-day orbit within the star's habitable zone .
Kepler-1638b was thought to be a possibly habitable planet with a radius smaller than 2 R 🜨 after the validation. However based on the later measurement of host star parallax by Gaia , the radius of the planet was revised upward to 3.226 +0.201
K2-22b (also known as EPIC 201637175 b) is an exoplanet 801 ly from Earth, rapidly orbiting the red dwarf K2-22 with an orbital period of 9.145872 hours. [2] It has a mass of 0.02 M E and a radius below 0.71 M E. [3] The planet was not detected in the K2 photometry. K2 photometry reveals the presence of an anomalous light curve consistent with ...
TrES-2b (also known as Kepler-1b or GSC 03549-02811b) is an extrasolar planet orbiting the star GSC 03549-02811 located 750 light years away from the Solar System. The planet was identified in 2011 as the darkest known exoplanet , reflecting less than 1% of any light that hits it.
[22] The size of the habitable zone is directly proportional to the mass and luminosity of its star, so the larger the star, the larger the habitable zone and the farther from its surface. [ 5 ] Red dwarfs, the smallest of the main sequence, have a very small habitable zone close to them, which subjects any potentially habitable planets in the ...
