Colliding Planets Near ASASSN-21qj: Maybe
They were looking for supernovae. What they found may become a double planet, like the Earth-Moon system, once it cools down. Or a planet with a giant moon, again like the Earth-Moon system. Then again, an oddly-uneven dusty disk may be orbiting this young, very "Sun-like" star. Either way, ASASSN-2qj is much more interesting than it was a few years back. strong>Barycenters and Binaries: Briefly Rabbit Holes and an ‘Assassin Star’ Professional Scientists, Amateur Astronomers, Teamwork and Twitter/X "...So Slow Smart" ASASSN-21qj: Once Obscure, Now Intriguing A Very Sun-Like Star Uncertainty and Science '...A Star to Steer By...'
