The average distance from Kepler-22b to its host star Kepler-22 is about 15% less than the distance from Earth to the Sun [16] but the luminosity (light output) of Kepler-22 is about 25% less than that of the Sun. [7] This combination of a shorter average distance from the star and a lower stellar luminosity are consistent with a moderate ...
Kepler-22b is at a distance of 600 light-years, in the Cygnus constellation. [48] It completes one orbit around its G5V-type star every 290 days. [53] Its radius is 2.35 R ⊕ and its estimated mass, for an Earth-like density, would be 20.36 M ⊕. If the planet's atmosphere and albedo were similar to Earth's, its surface temperature would be ...
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 ]
Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin [4] [5] based on its characteristics; also known by its Kepler object of interest designation KOI-7016.01) is a candidate [6] [7] super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system discovered by the Kepler space telescope.
NASA has characterized Kepler's orbit as "Earth-trailing". [61] With an orbital period of 372.5 days, Kepler is slowly falling farther behind Earth (about 16 million miles per annum). As of May 1, 2018, the distance to Kepler from Earth was about 0.917 AU (137 million km). [3]
By Irene Klotz BOSTON (Reuters) - Astronomers have discovered a new type of rocky planet beyond the solar system that weighs more than 17 times as much as Earth while being just over twice the ...
However, the planet is likely a mini-Neptune given its size. The planet has an ESI of 0.72, similar to that of Mars and Kepler-22b. [3] [4] The equilibrium temperature could range from a comfortable 317 K (44 °C; 111 °F) to a chilly 239 K (−34 °C; −29 °F), both within the thermal amplitude of the Earth. [2]
KOI-5715.01 is an exoplanet candidate that orbits the K-type dwarf star KOI-5715, located approximately 2,964 light-years from Earth in the constellation of Cygnus.It was identified in 2015 through an analysis of light curve data obtained by the Kepler space telescope.
