PSO J318.5-22 is a confirmed,[1][2] extrasolar object and candidate planet that does not appear to be orbiting a star. It is approximately 80 light-years away, and belongs to the Beta Pictoris moving group of stars.[3] The object was discovered in 2013 in images taken by the Pan-STARRS PS1 wide-field telescope. The object's age is inferred to be 12 million-years, the same age as the Beta Pictoris group.[4]
The team leader Dr Michael Liu of the Institute for Astronomy at the University of Hawaii stated “We have never before seen an object free-floating in space that looks like this. It has all the characteristics of young planets found around other stars, but it is drifting out there all alone"[5]
