Reminder that while it's not Lemmy, you can see the same stuff and more if you join Mbin. The power of the Fediverse is that there are lots of ways to do things, important for situations like this.
Ironically, I haven't looked into the current situation with .io lately, so I might be doing the same thing eventually. But being such a huge domain, there might be some adjustment to avoid dropping so many websites.
Possible, measuring the orbit will determine that likelihood. The article gives a few other formation possibilities as well. Finding a few other systems like this will help narrow down what exactly happened here. It doesn't seem that impossible to me, not like the title implies, given that while the star is low mass for a star, it's still a large mass, and the planet isn't that huge (50% less mass than Saturn despite being a bit larger in size).
This just sounds like an extension of our understanding of how things are in the universe similar to pre-Voyager thoughts on what they'd find from our own system's planets and moons. What we found was each place was unique with its own fascinating discoveries and not "just another rock". Seems we're finding that out for other solar systems as well.
