WebJ1407b ain't no regular planet, it's a brown dwarf, and its ring game is off the hook. The way those rings look is more like a protoplanetary disk than a regular ring system, and it's orbit is whack, like it might not even be orbiting anything steady. It's crazy cool to study stuff like J1407b because it helps us learn more about how planets ...
