The name J1407b follows the exoplanet naming convention by adding the letter "b" after the host star's name. [5] At the time of J1407b's discovery, V1400 Centauri was known as "J1407", which is the shortened form of the star's full SuperWASP catalogue designation 1SWASP J140747.93–394542.6.
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]
The most recent parallax measurements by the Gaia spacecraft indicate V1400 Centauri is located 450.8 ± 0.9 light-years (138.2 ± 0.3 parsecs) from the Sun. [1] Observations of V1400 Centauri's position over time have shown that it has a southwestward [b] proper motion consistent with that of the Scorpius–Centaurus association, an OB ...

The moons of the trans-Neptunian objects (other than Charon) have not been included, because they appear to follow the normal situation for TNOs rather than the moons of Saturn and Uranus, and become solid at a larger size (900–1000 km diameter, rather than 400 km as for the moons of Saturn and Uranus).
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. [5] [6] Two potential exomoons that may orbit rogue planets have also been detected by microlensing.
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.
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.
