DI Pegasi is a star system with two eclipsing stars in its center that orbit each other every 17 hours and 5 minutes and two smaller stars on very wide orbits that gravitationally tug on the central two stars, which has the effect that the variability of the star system's brightness seems to change over decades of time.…
