HONOLULU, Oct. 9 (UPI) -- An exotic young planet free-floating through the Milky Way galaxy rather than orbiting any star is practically a newborn in cosmic terms, astronomers say.
Dubbed PSO J318.5-22, the planet without a host star is 80 light-years away from Earth and has a mass only six times that of Jupiter. It formed a mere 12 million years ago, researchers said -- a newborn in planet lifetimes.
