CD-35 2722
The CD-35 2722 stellar system is located 71 lightyears from the Solar system.[1] In the system a red dwarf star, CD-35 2722 A orbits with a brown dwarf CD-35 2722 B.
The recent discovery of an object 0.9 times the mass of Planet Jupiter, orbiting the brown dwarf, has triggered discussion over how it should be classified.[2] Some commentators have described it as the first exomoon to be discovered, implying the brown dwarf should be treated as a planet.
CD-35 2722 A is of stellar type M1, and is forty percent the mass of Sol, our sun.[1] CD-35 2722 B is 37 times the mass of Jupiter, when the mass of brown dwarf's lie between 13 times and 80times the mass of Jupiter.

CD-35 2722 is a star system located approximately 73 light-years from the Sun. The primary star, CD-35 2722 A, is an object with an estimated mass of 0.4 solar masses. The system is notable for its substellar companion, CD-35 2722 B, a brown dwarf—an object too small to sustain the hydrogen fusion that powers typical stars—which serves as the host for the recently identified satellite candidates.
