What does an object break up due to gravity in intitle forces as it approaches a planet

It passes the Roche limit a break due tidal force.

Explanation:

The name Roche limit is due to famous scientist Edouard Roche.  It is known as the minimum distance which is smaller object can exist and as a body held together by itself gravity. Roche limit is also called Roche Radius.

Its minimum distance is from the center of the planet. For formation it allows the material to come together. The example is large enough moon.
