The Fragmentation of Comets
Every body is held together by two forces, its self-gravitation and its internal strength due to molecular bonding.
fragmentation The breaking up of a large object into many smaller pieces (for example, as the result of high-speed collisions between planetesimals and protoplanets in the early solar system).
Fragmentation - A possible explanation for the origin of a close binary pair of stars in which a collapsing cloud breaks into several pieces, each of which becomes a star
Frequency - The number of oscillations per second of a wave ...
Fragmentation is the process by which the casing of an artillery shell , bomb, grenade, etc is shattered by the detonate high explosive filling....
Gaseous Fragmentation
The systematic breakup of a gas cloud into smaller and smaller subunits as the gas cools and continues to collapse.

However, fragmentation of differentiated bodies yields distinct meteorite types. At least one asteroid with its original basaltic surface, 4 Vesta, survives to this day.
The largest satellite of Jupiter. Radius 2635 km (slightly larger than Mercury). Mass about 1.65 × 1026 g; period 7.155 days; e = 0.0015. [H76]

The fragmentation and gravitational collapse of an interstellar cloud of gas and dust, triggered perhaps by nearby supernova explosions, may have led to the formation of a primordial solar nebula.
Low mass stars form through a process of fragmentation and gravitational collapse inside a giant cloud of molecule hydrogen. "The question has always been, do high mass stars form in the same way?" says Davies.
This destruction is the result both of ablation (the loss of mass from the surface of the meteoroid by vaporization or as molten droplets) and of fragmentation caused by aerodynamic pressure that exceeds the crushing strength of the meteoroid.
The formation of stars begins with the collapse and fragmentation of molecular clouds into very dense clumps. These clumps initially contain ~0.01 solar masses of material, but increase in mass as surrounding material is accumulated through accretion.
Young stars are social---fragmentation of the giant molecular cloud produces protostars that form at about the same time. Stars are observed to be born in clusters. Other corroborating evidence for this is that there are no isolated young stars.
All inner moons are intimately connected to the rings of Uranus, which probably resulted from the fragmentation of one or several small inner moons.
Although present-day meteorites are the products of a long series of events that caused physical fragmentation, ...
The shape of Amalthea is controlled largely by impact cratering and fragmentation. In contrast, Io has gravity sufficient to form it into a slightly flattened sphere.
The restricted cooling possibilities mean that only masses in the rough range 80-300 solar masses formed these stars, without further fragmentation as we see today.
Very large meteoroids may strike the ground with a significant fraction of their cosmic velocity, leaving behind a hypervelocity impact crater. The kind of crater will depend on the size, composition, degree of fragmentation, ...
These accreted during the formation of the Solar System and thereafter suffered collisions leading to fragmentation. This hypothesis suggests that only a few of the larger asteroids are still intact.
where n is the particle number density, m is the mass of the 'average' gas particle in the cloud and T is the gas temperature.

Hence, either the object formed independently from fragmentation of the original Solar nebula, ...
These fragments are known as protostars because they are the bits that will eventually form into stars. As a cloud of gas collapses it is compressed, and as gas is compressed it is heated. The heating stops the process of fragmentation but it is not ...
More likely scenarios involve capture with a dense stellar environment, fragmentation of the collapsing birthcloud, and condensation of a companion from a the circumstellar disk that surrounds a new-born star.
