In this PBS Space Time video the forming solar system of Formalhaut is explored, with lots of Lord of the Rings puns to go around ever since the now infamous “Eye of Sauron” photo was released. Interestingly the star is a member of a tristellar system, it’s stellar siblings are a red dwarf and a flare star respectively.
Formalhaut’s solar system is also (probably) home to two planets, a hot Jupiter and a probably terrestrial planet called “Dagon,” how’s that for a cool name? Interestingly enough the orbit of Dagon indicates it was formed further in, closer to Formalhaut proper, but was thrown out into its current orbit by a close encounter with the aforementioned hot Jupiter. Something similar is posited to have happened in our solar system early on with the gas giants, as they all formed relatively close together but something threw them further apart.
Formalhaut may very well be a glimpse into what would have happened during the formation of our own solar system, as it is a solar system in formation right now as we speak.
