Jove is the sixth and largest planet in the Kerbos System . It has 2 extensive sets of rings.
"Jove was discovered when kerbal scientists measured perturbations in Byr’s orbit that can only be caused by a gas giant even more massive than itself. Soon after its discovery, a Jove transit in front of Kerbos allowed kerbal astronomers to detect a large network of rings around this world. Later analysis showed that the planet actually hosts two separate rings systems, one inner and one outer, which is something that has never been observed around any other planet before. This unique feature, as well as Jove’s large system of unexplored moons, makes the scientific community eager to send exploratory missions here to get a closer look."
- Jove was discovered using the Transiting Timing Variations method, which measures when a planet transits, and if it transits before or after predicted
