PSO J318.5-22
PSO J318.5-22 is an object of planetary mass that does not orbit a star . Its mass is estimated at 6.5 Jupiter , its age at 12 million years. It belongs to the Beta Pictoris group and is around 80 light years from Earth. Since his measured values are not superimposed by a central star, the scientists hope to gain new knowledge about the origin and development of Jupiter-like celestial bodies in general and especially of objects of planetary mass without a central star.
The celestial body was discovered in 2013 at the coordinates 21h 14m 8s ( right ascension ) and 22 ° 51 '36 "( declination ) using the Pan-STARRS telescope.
