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 ...
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.
There are 293 confirmed moons in our cosmic neighborhood. By studying these worlds, astronomers hope to learn about ancient asteroid collisions, space volcanoes, and the origins of life itself.
An exomoon or extrasolar moon is a natural satellite that orbits an exoplanet or other non-stellar extrasolar body. [2] Exomoons are difficult to detect and confirm using current techniques, [3] and to date there have been no confirmed exomoon detections. [4] However, observations from missions such as Kepler have observed a number of candidates.

Nineteen moons are large enough to be round, and two, Titan and Triton, have substantial atmospheres The number of moons discovered in each year until November 2019 Mercury , the smallest and innermost planet, has no moons, or at least none that can be detected to a diameter of 1.6 km (1.0 mi).
