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.
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. [1]
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.
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]
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.

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 ...
