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.
This is a list of unconfirmed exoplanets discovered or detected by the NASA Kepler mission (Kepler Candidates from the NASA Exoplanet Archive) that are potentially habitable. [ 1 ] [ 2 ] Those already confirmed are listed by their Kepler names in the list of potentially habitable exoplanets , and the data may differ when the planets are confirmed.
K2-288Bb (previously designated EPIC 210693462 b) is a super-Earth or mini-Neptune exoplanet orbiting in the habitable zone of K2-288B, a low-mass M-dwarf star in a binary star system in the constellation of Taurus about 226 light-years from Earth. [1] [2] [3] It was discovered by citizen scientists while analysing data from the Kepler space ...
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 around 22 °C. [54] It was the first exoplanet found by the Kepler telescope belonging to the habitability zone of its star. [55]
Kepler-452 is a G-type main-sequence star located about 1,810 light-years away from Earth [1] in the Cygnus constellation. [5] Although similar in temperature to the Sun, it is 20% brighter, 3.7% more massive and 11% larger. [6] [7] Alongside this, the star is approximately six billion years old and possesses a high metallicity. [3]
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.
Planet Hunters is a citizen science project to find exoplanets using human eyes. It does this by having users analyze data from the NASA Kepler space telescope and the NASA Transiting Exoplanet Survey Satellite. [1] [2] It was launched by a team led by Debra Fischer at Yale University, [3] as part of the Zooniverse project. [4]
On 31 August 2017, astronomers at the Hubble Space Telescope reported the first evidence of possible water content on the TRAPPIST-1 exoplanets. [11] [12] TRAPPIST-1f has a radius about the same as Earth, at around 1.045 R 🜨, but was initially thought to have only about two thirds of Earth's mass, at around 0.68 M E. So, it was considered ...
