New discovery is likely to be a rocky world in the ‘Goldilocks’ zone of its parent star where the temperature is just right for liquid water to flow
Earth-like Planets Kepler-438b Kepler-438b orbits a red dwarf star roughly 470 light-years from Earth. The planet is considered to be very similar to Earth in terms of radius and mass, but is likely not a habitable planet, according to astronomers. That's because, according to a 2015 study, Kepler-438b's parent star is extremely volatile, sending out "superflares" that are 10 times as powerful as anything recorded on the sun.
