Visions of the Future: PSO J318.5-22

Travel Posters

Discovered in October 2013 using direct imaging, PSO J318.5-22 belongs to a special class of planets called rogue, or free-floating, planets. Wandering alone in the galaxy, they do not orbit a parent star. Not much is known about how these planets come to exist, but scientists theorize that they may be either failed stars or planets ejected from very young systems after an encounter with another planet. It is one of the space-tourism posters NASA's Jet Propulsion Laboratory released to the public.
