According to Dvice: “Another interesting thing about the exomoon is that its planet does not seem to be actually orbiting a star itself. Scientists believe both the planet and exomoon may have been kicked out of its system for getting too close to its star. The exomoon might have even been a planet, as its mass is large: about half that of Earth’s. If the Notre Dame scientists are correct, this exomoon and its planet would be unlike anything we’ve seen before.”
