J1407b has been referred to as a “Saturn on steroids” or “Super Saturn” due to its massive system of circumplanetary rings, which is about 640 times that of Saturn’s rings. It is an exoplanet located 434 light years from Earth in the constellation of Centaurus and is the only known exoplanet with rings similar to Saturn.
If this planet swapped places with Saturn, its rings would dominate the Earth’s sky and appear many times larger than a full moon. There is a large gap halfway through the ring system, and a Mars-sized exomoon may orbit the planet within this gap. If aliens live on this exomoon, they have an extraordinary view looking up into the sky.
