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.
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]
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 ...
Illustration of the inferred size of the super-Earth CoRoT-7b (center) in comparison with Earth and Neptune. A Super-Earth or super-terran or super-tellurian is a type of exoplanet with a mass higher than Earth, but substantially below those of the Solar System's ice giants, Uranus and Neptune, which are 14.5 and 17.1 times Earth's, respectively.

The list includes planets within the range of 0.8–1.9 Earth masses, below which are generally classed as sub-Earth and above classed as super-Earth. In addition, only planets known to fall within the range of 0.5–2.0 Earth radius (between half and twice the radius of the Earth) are included.
