Roche and limit
At that time, the orbit of Shoemaker – Levy 9 passed within Jupiter's Roche limit, and Jupiter's tidal forces had acted to pull the comet apart.
The comet had apparently passed extremely close to Jupiter on July 7, 1992, just over above the planet's cloud topsa smaller distance than Jupiter's radius of, and well within the orbit of Jupiter's innermost moon Metis and the planet's Roche limit, inside which tidal forces are strong enough to disrupt a body held together only by gravity.
There are three ways that planetary rings ( the rings around planets ) have been proposed to have formed: from material of the protoplanetary disk that was within the Roche limit of the planet and thus could not coalesce to form moons ; from the debris of a moon that was disrupted by a large impact ; or from the debris of a moon that was disrupted by tidal stresses when it passed within the planet's Roche limit.
Several of Jupiter's small innermost moons, namely Metis and Adrastea, are within Jupiter's ring system and are also within Jupiter's Roche limit.
The Roche limit is the distance from a planet at which tidal effects would cause an object to disintegrate because the differential force of gravity from the planet overcomes the attraction of the parts of the object for one another.
* Roche limit
Tidal interactions also cause Triton's orbit, already closer to Neptune than the Moon's to Earth, to slowly decay further ; predictions are that some 3. 6 billion years from now, Triton will pass within Neptune's Roche limit.
If its density is similar to Amalthea's, Metis's orbit lies within the fluid Roche limit ; however, since it has not broken up, it must lie outside its rigid Roche limit.
* Roche limit
* 1849 – Édouard Roche finds the limiting radius of tidal destruction and tidal creation for a body held together only by its self gravity, called the Roche limit, and uses it to explain why Saturn's rings do not condense into a satellite
Inside the Roche limit, orbiting material will tend to disperse and form rings, while outside the limit, material will tend to coalesce.
The term is named after Édouard Roche, the French astronomer who first calculated this theoretical limit in 1848.
Typically, the Roche limit applies to a satellite disintegrating due to tidal forces induced by its primary, the body about which it orbits.
A weaker satellite, such as a comet, could be broken up when it passes within its Roche limit.
Since tidal forces overwhelm the gravity that might hold the satellite together within the Roche limit, no large satellite can gravitationally coalesce out of smaller particles within that limit.

Roche and sometimes

Armthorpe ( Ernulfestorp ) was recorded in the Domesday Book as being the property of the monks of Roche Abbey near Maltby, who had a grange there at which an official resided who managed this part of the estates of the establishment and who was sometimes a brother of the house: they had also an officer called their forester.

Roche and referred
Kevin Roche has been referred to as the " first to see architecture and nature as one.

Roche and radius
When a star in a binary fills its Roche lobe ( either due to being very close to its companion or having a relatively large radius ), it begins to lose matter, which streams towards the neutron star.
* Édouard Roche finds the limiting radius of tidal destruction and tidal creation for a body held together only by its self gravity, called the Roche limit, and uses it to explain why Saturn's rings do not condense into a satellite.
* Roche limit ( also known as the " Roche radius "), a concept in celestial mechanics

* On Point Au Roche, part of Beekmantown, New York, there is a privately owned, historic lighthouse.
In astrophysics, mass transfer is the process by which matter gravitationally bound to a body, usually a star, fills its Roche lobe and becomes gravitationally bound to a second body, usually a compact object ( white dwarf, neutron star or black hole ), and is eventually accreted onto it.
Antonio Canizares Llovera is the Cardinal Prefect, Archbishop Arthur Roche is the Secretary, and Father Anthony Ward, S. M., is Under-secretary.
The Island of South Georgia is said to have been first sighted in 1675 by Anthony de la Roché, a London merchant, and was named Roche Island on a number of early maps.
* Roche lobe, the region of space around a star in a binary system within which orbiting material is gravitationally bound to that star
Hercules X-1 is composed of a neutron star accreting matter from a normal star ( HZ Herculis ) probably due to Roche lobe overflow.
It is easy for the impact ejecta to be lost from the satellites into space because the satellites ' surfaces lie fairly close to the edge of their Roche spheres due to their low density.
In fact, the size of the equatorial ridge is comparable with the expected Roche lobe of the moon.
Detached binaries are binary stars where each component is within its Roche lobe, i. e. the area where the gravitational pull of the star itself is larger than that of the other component.
A contact binary is a type of binary star in which both components of the binary fill their Roche lobes.
As a main sequence star increases in size during its evolution, it may at some point exceed its Roche lobe, meaning that some of its matter ventures into a region where the gravitational pull of its companion star is larger than its own.
The result is that matter will transfer from one star to another through a process known as Roche Lobe overflow ( RLOF ), either being absorbed by direct impact or through an accretion disc.

Roche and distance
The Roche limit for a rigid spherical satellite excluding orbital effects, is the distance,, from the primary at which the gravitational force on a test mass on the surface of the object is exactly equal to the tidal force pulling the object away from the object:
It is different from the Roche limit which is the distance at which an object held together only by gravity begins to break up due to tidal forces.
