Double Star with an outer planet
In a double star system, a planet can orbit around both
The planet feels the combined gravity of the two stars. However, the planet’s distance to each star is constantly varying, so that the gravity force, and the planet’s orbit, tends to be erratic.
This means that the climate on Luke Skywalker’s home planet Tatooine would have some wild excursions.
