This star survived a close call with a black hole. Eventually, it will become a planet

CNN — A red giant star strayed too close to a supermassive black hole in a galaxy 250 million light-years away. “It is now caught in an elliptical orbit around the black hole, making one trip around about once every nine hours.” The study published last month in the Monthly Notices of the Royal Astronomical Society. The same is true in a recent study of a star seen in a rosette orbit around the supermassive black hole at the center of our Milky Way galaxy. This will cause the white dwarf star to spiral further away from the black hole, slowing the amount of mass lost from the star.
