Satellite of a Brown Dwarf

An Io-like satellite body orbits a T-class brown dwarf, itself a companion of a red dwarf star. Nebulae can be seen in the background. Another satellite of the brown dwarf can be seen in the distance. This situation brings up an interesting question: are satellites of a brown dwarf moons or planets? A brown dwarf is too small to be a star, but also big enough to be different from planets, also having a different formation mechanism than planets, so what do we call what orbit them?
