Size is often thought to be a significant factor, as planets of Earth's size are thought more likely to be terrestrial in nature and be capable of retaining an Earth-like atmosphere. [26] 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 ...
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.
At the time of its discovery, Kepler-78b was the exoplanet most similar to Earth in terms of mass, radius, and mean density. [7] The planet is approximately 1.69 times the mass and 1.12 times the radius of Earth. [8] The acceleration due to gravity on the planet's surface is about 11 m/s 2 (25 mph/s), slightly greater than Earth's surface ...
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, dubbed Proxima b because it orbits Proxima Centauri, is thought to be a rocky and slightly more massive than Earth -- but that's not all. Scientists discover Earth-like planet orbiting ...
Kepler-10b is the first confirmed terrestrial planet to have been discovered outside the Solar System by the Kepler Space Telescope. [7] Discovered after several months of data collection during the course of the NASA-directed Kepler Mission, which aims to discover Earth-like planets crossing in front of their host stars, the planet's discovery was announced on January 10, 2011.
An international team of astronomers is calling this one a 'game changer.'
Kepler-62e (also known by its Kepler Object of Interest designation KOI-701.03) is a super-Earth exoplanet (extrasolar planet) discovered orbiting within the habitable zone of Kepler-62, the second outermost of five such planets discovered by NASA's Kepler spacecraft.
