NASA TESS Discovers Super Earth That Could Have Life, And it is 31 Light Years Away
GJ 357 d, a super-Earth, could provide Earth-like conditions and orbits the dwarf star every 55.7 days at a distance about one-fifth of Earth's distance from the sun
Scientists have characterised the first potentially habitable world outside our own solar system located about 31 light-years away. The super-Earth planet — named GJ 357 d — was discovered in early 2019 owing to NASA's Transiting Exoplanet Survey Satellite (TESS), a mission designed to comb the heavens for exoplanets, according to the research published in the Astrophysical Journal Letters.
"This is exciting, as this is humanity's first nearby super-Earth that could harbour life — uncovered with help from TESS, our small, mighty mission with a huge reach," said Lisa Kaltenegger, associate professor of astronomy at Cornell University in the US and a member of the TESS science team. The exoplanet is more massive than our own blue planet, and Kaltenegger said the discovery will provide insight into Earth's heavyweight planetary cousins.
Answer:
A super-Earth is an extrasolar planet 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.
