If we're calling Brown Dwarfs 'Failed Stars' and 'Substellar objects' then perhaps it makes more sense to call this Jupiter sized object a 'planet' rather than a 'moon'
There's every chance the Gas Giant has moons as well... -

This is where Brown Dwarfs are made.
These are what comes between a world like Jupiter and a red dwarf star, the Universe is full of them. -

Two failed stars given a second chance. This is the first mass transfer process seen in a brown dwarf pairing ever discovered. Go, go, my brown little stars.
..., a team of scientists has discovered a tightly orbiting pair of brown dwarfs that are working together to combat this "failure." One brown dwarf is actively siphoning material from its companion, meaning it could achieve the mass needed to trigger nuclear fusion in its core and become a fully-fledged star. Either that, or these brown dwarfs will collide and merge, birthing an entirely new star with enough mass to trigger nuclear fusion.

Spitzer + HST parallaxes of 13 late T and Y dwarfs: https://arxiv.org/abs/2603.08984 -> "We present astrometric measurements for 13 cold #BrownDwarfs in the solar neighborhood (d < 20pc). By combining archival Spitzer data with our own Hubble Space Telescope (HST) observations, we achieve parallax uncertainties typically around 10%. Using Spitzer and HST photometry we compare our targets with other known late T and Y dwarfs in the Solar neighborhood, confirming that there is large intrinsic scatter in the near- and mid-infrared absolute magnitudes and colors of this population, further highlighting the diversity observed spectroscopically by several James Webb Space Telescope (JWST) programs."
