1SWASP J1407 b

1SWASP J1407 b (also known as J1407b, V1400 Cen b and its nickname, Super Saturn) is an brown or red dwarf probably orbiting a pre-main sequence, variable star V1400 Cen, otherwise known as Mamajek's object, however it may also be a rogue object, not orbiting any star. J1407b is estimated to have a mass of 20 Jupiter masses, with a margin of error of 6 Jupiter masses, and it may have the largest known ring system of any substellar object, however these rings could potentially be a protoplanetary disk or a dusty circumplanetary disk. Its discovery sparked prominent popularity and controversy as how such an exoplanet can hold a massive ring system orbiting the star. The size of the circumplanetary disk around J1407b is estimated to be around 90 million km (55 million mi) or about 0.6 AU. If the Sun was replaced with J1407b, its circumplanetary disk would go past Mercury's orbit, almost reaching the orbit of Venus. J1407b was discovered from an observation of an usually long and intricate series of deep-dimming periods from Mamajek's Object, although it hasn't repeated ever since and its unknown it will make an appearance again.
