Astronomers Spot Potential Earth-like Planet That Could Be Colder Than Mars
Scientists have uncovered a promising exoplanet candidate, HD 137010 b, that is similar in size and orbital distance to Earth but may be much colder, possibly even cooler than Mars. The world orbits a dimmer Sun-like star about 146 light-years away and lies near the outer edge of the star’s habitable zone. Confirmation will require observing repeat transits, which are expected only about once a year, making follow-up studies challenging.
