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.
The planet is about the size of Venus, so slightly smaller than Earth, and may be temperate enough to support life, the researchers said. Dubbed Gliese 12 b, the planet takes 12.8 days to orbit a ...
A study of atmospheric evolution in Earth-size planets in habitable zones of G-Stars (a class containing the Sun, but not Kepler-186) suggested that 0.8–1.15 R 🜨 is the size range for planets small enough to lose their initial accreted hydrogen envelope but large enough to retain an outgassed secondary atmosphere such as Earth's.

The planet was found using data from the NASA Kepler Space Telescope, K2, and the Transiting Exoplanet Survey Satellite.K2-415b was discovered in February 2023. [2]K2-415b is approximately 1.015 times the radius of Earth and is less than 7.5 times the mass of Earth.
Astronomers have found an Earth-sized planet shockingly close to our own. The world – known as HD 63433d – is the closest and youngest Earth-sized world ever to be found.
Planet is the size of Venus and is likely to have a relatively cool atmosphere ... Scientists have found a new Earth-like planet that could support alien life – just 40 light-years away.
Kepler-62e is located about 990 light-years (300 parsecs) from Earth in the constellation of Lyra. [3] The exoplanet was found using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured.
Seven Earth-sized planets have been discovered orbiting a nearby star, three of which appear to be warm enough to sustain life, according to astronomers from NASA and the European Southern ...
