That’s no planet! It’s one to five moons.
Most planets in our solar system have multiple moons, from Mars’ 2 to Saturn’s ~82. Today’s paper explores the stability and detectability of multi-”exomoon” systems orbiting planets beyond our solar system.
Was Uranus Impacted?
Uranus spins on its side, and its five main moons have a unique composition and mass distribution. Ever wondered why? Today’s paper offers an explanation.
Formation of the Galilean Moons
New simulations show that a chain of orbital resonances can reproduce the Galilean system
A Moon’s Moon?!
Is it possible for moons to have moons? Today’s authors look at our own solar system for answers!
Boomerang, Slingshot, or Torque-Dependent? How to Classify Your Favorite Ring-Satellite System
When moons and rings orbit together, the results can be crazy. This paper proposes three regimes to more easily understand these complex interactions.
Moonetesimals likely form relatively quickly
The absence of dusty circumplanetary disks around young giant planets suggests moonetesimals grow relatively quickly.
