The super-Earth discovery was a fortuitous event that UC described as "one in a million."
The GJ 357 system has three planets that we know of. The astronomers used a gravitational microlensing technique to spot the planet.
A super-Earth is a planet that has a mass between one and 10 times that of Earth.
The planet's year lasts about 617 Earth days, even though its orbit falls somewhere between those of Earth and Venus around our sun.
But the team of scientists that discovered …
The first super-Earths were discovered by Aleksander Wolszczan and Dale Frail around the pulsar PSR B1257+12 in 1992.
The two outer planets (Poltergeist and Phobetor) of the system have masses approximately four times Earth—too small to be gas giants.The first super-Earth around a main-sequence star was discovered by a team under Eugenio Rivera in 2005. . Potentially habitable 'super-Earth' discovered just 31 light-years away Follow-up research could reveal if the planet is rocky or has oceans. Using data from NASA's Kepler space telescope, two NASA interns and a team of amateur astronomers have found a new 'super Earth'..
NASA has just announced the discovery of a new super-Earth that could be both habitable and accessible. Roughly twice the size of Earth… Earlier this week, NASA announced the discovery of a possible Earth-like planet, located just 31 light years away - a hop, skip and a jump in cosmic terms - that may be able to support life. Researchers have found a Super-Earth exoplanet they describe as "one in a million" in deep space.
