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.
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.
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]

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.
Comment: The J1407b article was converted from redirect into article as a result of a split from the V1400 Centauri article. I began slowly expanding V1400 Centauri on 8 July 2024, but I did not add much to the J1407b section until 24 July 2024. As of today, it's been 5 days since I significantly expanded the J1407b section.
This video shows an artist's impression of the free-floating planet CFBDSIR J214947.2-040308.9.. A rogue planet, also termed a free-floating planet (FFP) or an isolated planetary-mass object (iPMO), is an interstellar object of planetary mass which is not gravitationally bound to any star or brown dwarf.
HD 189733 b is an exoplanet in the constellation of Vulpecula approximately 64.5 light-years (19.8 parsecs) away [7] from the Solar System.Astronomers in France discovered the planet orbiting the star HD 189733 on October 5, 2005, by observing its transit across the star's face. [1]
