Can Moons Have Moons?

The video explains the basic science of orbits, where lighter objects orbit more massive ones. It explores the possibility of moons having their own moons, known as sub-moons, and the challenges they face due to gravitational forces from nearby massive bodies. The video discusses conditions that might allow sub-moons to exist, such as sufficient distance from the host planet. It highlights potential candidates for sub-moons, like Jupiter's Callisto and Saturn's Titan, and mentions recent research on exoplanets like Kepler-1625b. The discovery of sub-moons could enhance our understanding of planetary formation and dynamics.

Discuss the significance of discovering sub-moons in relation to planetary formation.
