Can a binary or triple star system have exoplanets?

So as Robert Frost says, we have found such systems. Here's a little mathematical background as to what they can look like. So we can't solve three mutually gravitationally attracting bodies (the notorious three body problem), but we can get some... read more

Exoplanet Found in Triple Star System. HD 131399Ab is one of maybe a half dozen worlds found in triple-star systems. HD 131399Ab is one of the few exoplanets that have been directly imaged, and it's the first one in such an interesting dynamical configuration. read more

Prior to this study, all the planets discovered thus far in binary systems have been gas giants, including a binary system with more than one planet. It's possible, of course, that the moons of these exoplanets are habitable, but astronomers have no idea if rocky Earth-like planets in stable Earth-like orbits can form in these systems — though models suggest it is possible. read more

A star of interest lies in a triple star system. It is the third member and in a larger orbit around a tight binary system. As the tight binary system orbits, there will be periods in which they line up with the star of interest giving a minutely greater pull before relaxing the pull later in their orbit. read more
