The eclipse by J1407b was not discovered until 2010, by Mark Pecaut and Eric Mamajek, and was announced in 2012. J1407b's disk spans a radius of about 90 million kilometers (56 million miles) and consists of many rings and gaps which may indicate moons are forming in orbit around the object. It was initially thought to be orbiting V1400 ...
J1407) in 2007, may have a few moons based on gaps observed in its circumstellar disk or ring system. [1] Later studies have since found that J1407b is most likely a free-floating sub-brown dwarf or rogue planet, possibly less than 6 Jupiter masses. [2] 2012 — The confirmed hot Jupiter planet WASP-12b may also possess a moon. [3]
Mamajek's team initially hypothesized that J1407b is a ringed exoplanet or brown dwarf orbiting the star, [3]: 8 but that has since been disfavored by later studies. V1400 Centauri does not show repeating eclipses, telescope observations showed no orbiting companions, and the disk of J1407b would be unstable if it orbited the star, which ...

For impact-generated moons of terrestrial planets not too far from their star, with a large planet–moon distance, it is expected that the orbital planes of moons will tend to be aligned with the planet's orbit around the star due to tides from the star, but if the planet–moon distance is small it may be inclined.
“I have to be keenly aware of all those potential challenges and have a strategy to respond to each if they actually occur. So it’s playing some defense right now, getting the game plan ...
