Imagine, we now know that a planet can have three suns.

Maybe the center of mass of the three remains constant, and the planet
revolves around that. Seasons would be chaotic as hell. Winter could come
after Summer, and then after Spring.
AFAIK there are two ways this could work:
1) the planet circles very close around one of the stars
2) the planet circles very far away around all three stars

Lots of Greetings!
