J1407b is a substellar object, either a free-floating planet or brown dwarf, with a massive circumplanetary disk or ring system.It was first detected by automated telescopes in 2007 when its disk eclipsed the star V1400 Centauri, causing a series of dimming events for 56 days.

V1400 Centauri, also known as 1SWASP J140747.93−394542.6 or simply J1407, is a young, pre-main-sequence star that was eclipsed by the likely free-floating substellar object J1407b in April–June 2007.
The circumstellar disk or ring system of J1407b is about 0.6 astronomical units (90,000,000 km; 56,000,000 mi) in radius. [43] J1407b's transit of V1400 Centauri revealed gaps and density variations within its disk or ring system, which has been interpreted as hints of exomoons or exoplanets forming around J1407b. [43]
Motion interpolation of seven images of the HR 8799 system taken from the W. M. Keck Observatory over seven years, featuring four exoplanets. This is a list of extrasolar planets that have been directly observed, sorted by observed separations. This method works best for young planets that emit infrared light and are far from the glare of the star.
J1407b's rings span a radius of about 90 million kilometers (56 million miles) and may eventually form moons over time. Although initially thought to be orbiting V1400 Centauri, later studies suggest J1407b is likely an unbound object passing in front of the star. This is stripped down to what I think is the bare minimum.
