Now, thanks to a recent eclipse where planet J1407b lined up in front of host star J1407, scientists at the University of Rochester analyzed the way the light signal changed and got a clearer picture of J1407b’s ring system. Their findings: It’s roughly 200 times as large as the rings around Saturn, each of its more than 30 rings are tens of millions of miles wide, and there are gaps between the concentric rings that suggest the presence of exomoons similar to Saturn’s “shepherd” moons. The planet’s mass is 10 to 40 times greater than Saturn’s. More
