This Possible Earth-Sized Planet May Be Colder Than Mars

HD 137010 b is a possible Earth-sized exoplanet about 146 light-years away. Scientists detected only one possible transit in old Kepler data, so its existence has not yet been confirmed. If it is real, its surface temperature could be around −68°C—possibly colder than Mars. #HD137010b #exoplanetcandidate #possibleexoplanet #Earthsizedplanet #colderthanMars #frozenplanet #icyplanet #alienworld #planetbeyondoursolarsystem #Keplermission #NASAKepler #spacefacts #astronomyfacts #sciencefacts #exoplanetfacts #mysteriousplanet #habitablezone #cosmicdiscovery #educationalshorts #scienceshorts #spaceshorts #Shorts
