In theory, it could happen – one of the very first solutions to the three-body problem was this scenario. But it is very unlikely to be stable over time. You need the stars to have near equal mass and ...

(CNN) — It’s rare for astronomers to spot a planet in a star cluster. That’s partly why a cluster called Messier 67 is so special: We now know that it has three planets orbiting stars. Even more ...
