   Astronomers have discovered an exoplanetary system with two gas giant planets that are messing up each other's orbit. One planet has 3.8 Jupiter masses and orbits every 82 days, while the other has 1.4 Jupiter masses. There's also a mini-Neptune world in the system. The two giant planets are locked in a 2:1 orbital resonance, and because of their gravitational interactions, the heavier planet can vary in its orbit by up to 4 days.
