Evidence of first planet orbiting three stars discovered in dusty disc
One Sun is plenty for our solar system, but some planets have been found orbiting two stars at once. Now the ante has been upped again, with evidence emerging of a planet orbiting three stars at once.

Sets clock for 4 stars, one planet.

I found an exoplanet in the Kepler data orbiting 4 stars. That’s how I knew there were serious problems with data from the Kepler Space Telescope.

Gravitationally unstable ?

Could work.
Two likely ways would be

Two likely ways would be
- for the planet to be much closer to one star than the star was to the other stars
- for the planet to be much further from all the stars than the stars are to each other.
Agree. If it was found by occultation then it would have to be close to a single star.
Proxima Centauri b is an example of a stable planet in a 3 star system.
Otherwise, unlikely.
In my Kepler data study, the planet appeared to occult multiple stars at the same time. The only explanation was light from one star contaminating the light fields of the other stars. ie. the telescope focus was so bad that it failed to pin down which light was coming from which star.
