NASA’s Kepler Space Telescope has spotted a number of ‘free floating’ planets in deep space. The telescope discovered four rogue planets with a similar mass to Earth. However, none of them were attached to our solar system.
NASA Exoplanets shared the names of the two planets and wrote that it added to the total of 4,424 found exoplanets. The two planets were named Kepler-129d and GJ849c. (July 2021)
Free-floating planetary mass ‘may represent the end-states of disrupted exoplanetary systems’, according University of Manchester researchers.
