Description
In celestial mechanics , the Roche limit, also called Roche radius, is the distance from a celestial body within which a second celestial body, held together only by its own force of gravity , will disintegrate because the first body's tidal forces exceed the second body's gravitational self-attraction.[1] Inside the Roche limit, orbiting material disperses and forms rings , whereas outside the limit, material tends to coalesce . The Roche radius depends on the radius of the first body and on the ratio of the bodies' densities.
The term is named after Édouard Roche , who was the French astronomer who first calculated this theoretical limit in 1848.Wikipedia: Roche Limit

Looking through some older files and found this one from August, 2020

An example of this phenomenon can be found in Neptune's orbit: the orbit of its moon Triton is gradually decreasing, such that in a couple billion years, it'll enter the Roche limit and will either break apart or collide with the planet's atmosphere. Either way, something unhealthy.
