Remember that planet with a ring system much bigger than itself? J1407b I think. Only, it's unclear if the renderings of it that came out when it was first discovered really do describe it well?What I need to know is if such a thing *could* exist. Or was this idea just silly?

@futurebird Offhand, I think it would be possible but the planet would need to be extraordinarily dense to have a high enough gravitational pull to sustain the rings' orbits.

@futurebird responding in pure vibes, no math.For a moment I imagine the solar system as a very, very diffuse ring system around the sun. The orbital radius of Neptune is *kicks Google calculator a few times* seven thousand times bigger than the radius of the Sun. This gives me a very very vague mental rubric of "well I've seen a very dense object sustain orbiting matter on at least this scale, so I can't *immediately* reject the idea of an orbital system smaller than that…"

@futurebird I’d say yes, it can exist but pinging @mattkenworthy who would be the best person (as one of the original authors of that study) to answer your question.

@futurebird It could exist, but only for a very massive planet in a sufficiently distant orbit.It happens that @mattkenworthy is on here, for a primary source.

@futurebird Hi! Original author here :) The artwork is a reasonably good rendering, but the planet is too big, the rings are really HUGE. In our paper, I worked out what each ring should look like, but because we only have one wavelength, the colour of the rings is a guess, so we guess they're grey like Saturn's rings /1 https://kenworthy.space/projects/j1407b/

@martinvermeer @futurebird Spot on. At least, that's my hypothesis. What's needed is a second eclipse to confirm this specific system, or lots of others to show that this isn't a unique occurrence. I think most other astronomers are on the fence about this... they aren't comfortable about it, but they can't think of a better alternative given all the evidence and discussion.

@taoish All rings are larger in diameter but few this dramatically.

@futurebird I've seen ring systems you wouldn't believe in Elite Dangerous. Imagine *stars* with ring systems. It looks not unlike this.No idea how it might physically work. But it looks cool! :thinkhappy:

@futurebird Aaand This has just attracted the most interesting explanation of anything I've read in some time!TYVM! 😊
