It is precisely because of the short distance between them that it is like the intimacy between two lovers. Just like the relationship between the earth and the moon, because the moon has been guarding the earth and roche limit exists, the most suitable distance is maintained between them. Once close, the moon will be shattered and become the most beautiful halo.
Origin:
Roche limit was named by a French astronomer, because it was first obtained by Roche, and Roche was his name, so it was called Roche limit. The so-called roche limit is the limit of the distance between the planet and the satellite.
When the distance between this celestial body and the second celestial body is close to roche limit, they will have an impact. At this time, the gravity of the celestial body itself is equal to the tidal force caused by the second celestial body. But if their gravity is not equal to roche limit's, they will split into a second celestial body, so they will be far apart.
