A Super-Earth Is Found By The Astronomers Which Is Just 31 Light Years Away

A potentially liveable ‘super-Earth’ has been found just 31 light-years away from our solar system, astronomers introduced on Wednesday.

The planet, named GJ 357 d, is about six times bigger than Earth and orbits a dwarf sun GJ 357, a lot smaller than our own, every 55.7 days. The international group of astronomers that found the planet mentioned in a news release that it may “present Earth-like conditions.”

“With a thick atmosphere, the planet GJ 357 d may preserve liquid water on its surface like Earth, and we may select signs of life with telescopes that may quickly be on-line,” Lisa Kaltenegger, the director of the Carl Sagan Institute at Cornell and associate professor in astronomy, mentioned in a press release. “If GJ 357 d were to point out signs of life, it would be at the top of everybody’s travel list – and we might reply a 1,000-year-old query on whether or not we’re alone in the cosmos.”

Without an atmosphere, the planet would have an equilibrium temperature of 64 levels below zero, according to NASA, which might make it “more glacial than habitable.”

Whereas utilizing NASA’s planet-hunting Transiting Exoplanet Survey Satellite (TESS) in early 2019, Kaltenegger’s crew first found another planet GJ 357 b, a “hot Earth,” orbiting the dwarf sun.

The satellite finds different worlds by monitoring the closest and brightest stars for periodic dips in light. These dips, known as transits, recommend a planet could also be passing in front of its star.
