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.
It was not until 2015 that the first near-Earth sized candidate orbiting a solar candidate, Kepler-452b, was announced. [19] [20] On 11 January 2023, NASA scientists reported the detection of LHS 475 b, an Earth-like exoplanet – and the first exoplanet discovered by the James Webb Space Telescope. [21]
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.
K2-288Bb is unusual for having a radius not commonly seen among most exoplanets. At 1.90 R 🜨, it falls within the so-called Fulton gap between 1.5 and 2.0 R 🜨.This is the range of sizes where rocky super-Earths start to accumulate thick volatile layers and turn into mini-Neptunes. [2]

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]
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.
