The planet is named J1407b after the star it orbits, J1407. (Don't worry, astronomers are working on better names for exoplanets.) J1047b has 37 rings, with a total radius of the rings reaching 55 million miles. To put that in perspective, the distance from the Earth to the Sun is 92 million miles. J1407b is between 10 and 40 times the size of Jupiter. That's so huge that while scientists are pretty sure it's not a star, they are still trying to determine if it is a true exoplanet, or a brown dwarf an object that's neither a planet or a star, but stuck somewhere in between.
