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 closest exoplanets are those found orbiting the star closest to the Solar System, which is Proxima Centauri 4.25 light-years away. The first confirmed exoplanet discovered in the Proxima Centauri system was Proxima Centauri b, in 2016. HD 219134 (21.6 ly) has six exoplanets, the highest number discovered for any star within this range.
Located 31 light years from Earth, this planet is 1.26 times the mass of Earth and has a radius of 1.08 times the Earth's. Though Wolf 1069 b is likely tidally locked, its daylight side may still be habitable. It has similar characteristics to Proxima Centauri b and is one of the nearest discovered potentially habitable exoplanets to Earth.
Scientists have found a new Earth-like planet that could support alien life – just 40 light-years away. The planet is a remarkable discovery in the search for habitable worlds: it is slightly ...
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 ...
If such a planet exists, researchers say it would have a mass about 1.5 to 3 times that of Earth with an inclination of about 30 degrees. They say the theorised planet’s orbit would likely place ...
This is a list of exoplanets within the circumstellar habitable zone that are either under 10 Earth masses or smaller than 2.5 Earth radii, and thus have a chance of being rocky. [3] [1] Note that inclusion on this list does not guarantee habitability, and in particular the larger planets are more unlikely to have a rocky composition. [4]
At the time of discovery, with 5.5 Earth masses, the planet was less massive than the previous candidate for lowest-mass exoplanet around a main-sequence star, the 7.5 Earth mass Gliese 876 d. Since 2013, many Earth-sized or smaller planets around main-sequence stars have been detected by the Kepler spacecraft and others. [citation needed]
