A Super-Earth is a type of exoplanet with a mass higher than Earth 's, but substantially below those of the Solar System's ice giants, Uranus and Neptune, which are 14.5 and 17 times Earth's, respectively. [1] The term "super-Earth" refers only to the mass of the planet, and so does not imply anything about the surface conditions or habitability.
Oct 11, 2022 · The planet: GJ 1252 b. The discovery: GJ 1252 b, a rocky, terrestrial "super-Earth" discovered in 2020, has been given a closer look and astronomers have found that the exoplanet could have a very minimal atmosphere or possibly no atmosphere at all. The planet, which orbits an M-type star, is "the smallest exoplanet yet for which we have such ...
The innermost planet, TOI 270 b, is likely a rocky super-Earth about 25% larger than Earth. It orbits the star every 3.4 days at a distance about 13 times closer than Mercury orbits the Sun. Based on statistical studies of known exoplanets of similar size, the science team estimates TOI 270 b has a mass around 1.9 times greater than Earth’s.
6 days ago · An international team of astronomers has detected a new, Earth-sized planet just 55 light years away, orbiting an ultra-cool red dwarf star. The planet is only the second of its kind to be ...
6 days ago · Discovery Alert: An Earth-sized World and Its Ultra-cool Star. An artist’s concept of the exoplanet SPECULOOS-3 b orbiting its red dwarf star. The planet is as big around as Earth, while its star is slightly bigger than Jupiter – but much more massive. Our galaxy is a jewel box of red stars. More than 70% of the stars in the Milky Way are M ...
Dec 2, 2021 · Now, astronomers have discovered an ultra-short-period planet (USP) that is also super light. The planet is named GJ 367 b, and it orbits its star in just eight hours. The planet is about the size of Mars, and half as massive as the Earth, making it one of the lightest planets discovered to date. Orbiting a nearby star that is 31 light years ...
Aug 12, 2015 · An artist's conception shows the size of super-Earth 55 Cancri e compared to Earth. A ground-based telescope in Spain was able to identify 55 Cancri e, which suggests that telescopes on the ground ...
