3. The Planet with Enormous Planetary Rings
J1407 b has been discovered in 2012, and its data have been compiled and submitted for publication only recently. It is located 400 light years away from Earth. What is astounding about this planet is that it has a system of planetary rings, just like Saturn, and these rings are 200 times larger than the ones around Saturn. The rings are so big that if they belonged to Saturn, it would almost dominate the Earth’s sky, appearing larger than the Moon, and scientists also observed a 56-day eclipse of its host star. The gaps between the rings are believed to represent exomoons orbiting this exoplanet.
