Astronomers have found evidence of a massive object orbiting a brown dwarf in the CD-35 2722 system, raising the possibility that it could be the first moon ever discovered beyond our Solar System. The finding, based on observations from the European Southern Observatory's Very Large Telescope, is awaiting confirmation.

The star, Betelgeuse B, is 2.6 to 3.1 times bigger than our sun, with a diameter 1.8 to two times greater
