Here is a bit more information on this completely unusual find:

A rocky planet orbiting a brown dwarf has never been observed before. This system is therefore thought to be either a scaled-up version of a moon going around a planet or a scaled-down version of a planet going around a star. The ratio between the mass of the host brown dwarf and that of the planet is the same as the ratio between the Sun and Uranus and between Jupiter and Callisto (its second largest moon). The astronomers argue that this suggests the same mechanisms formed Uranus, Callisto and the new planet.

What do you think?  Is this more common throughout the galaxy and universe or completely rare?  Feel free to comment and we’re looking forward to hearing more.
