Gigantic ‘Keystone Super-Earth’ Found in Deep Space

An exoplanet is extremely hot and incredibly closeThe newly discovered planet’s mass is nearly ten times that of Earth, and temperatures on its surface reach over 1,000 degrees Celsius.A humongous rocky “super-Earth” exoplanet has been discovered in space, orbiting a distant star some 200 light years away via observations from NASA’s Transiting Exoplanet Survey Satellite spacecraft.The planet, designated TOI-1075b, has a mass ten times greater than that of Earth and the proximity to its host star results in temperatures at the planet’s surface reaching 1,050 degrees Celsius.TOI-1075b appears to be one of the largest super-Earth type planets discovered so far, NASA noted, adding that the study of this planet might “yield new insight into the formation of rocky planets like our own”.Science & TechIt’s a Marshmallow World!
