That star, Travesso, is MASSIVE. The reason you thought it was a planet is because it looks orange. It is actually a Red GIANT (I think the biggest in the sky) and I believe the whole of our Solar system could fit inside it) Inside that star is a vacuum far greater than anybody on Earth could make!
It is going to go POP soon (give or take a few million years) and will become a supernova. It has also got a mate up there which orbits around it, but it is very difficult to see because of the brightness of the primary. Amazing stuff
