Astronomers have found a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars. This is the first time we have strong evidence for one of these ‘polar planets’ orbiting a stellar pair. The surprise discovery was made using the European Southern Observatory’s Very Large Telescope (VLT).
Possibly. I didn’t dive in deeper to see if they even know the shape of the orbit. From my understanding a capture is very unlikely to have a near circular orbit. But planetary discs definitely aren’t captures, so something changed the stars in those.
