Here we show that the primordial asteroid belt could have been cleared efficiently if much of the original mass accreted to form planetsized bodies, which were capable of perturbing one another into unstable orbits. We provide results from 25 N-body integrations of up to 200 planets in the ...

Geography of the asteroid belt Geographyin its most-literal sense is a description of the features on the surface ofEarthor anotherplanet. Three coordinates—latitude, longitude, andaltitude—suffice for locating all such features. Similarly, the location of any object in thesolar systemcan be spec...
asteroid belt- the region of interplanetary space between Mars and Jupiter where most asteroids are found interplanetary space- the part of outer space within the solar system belt- an elongated region where a specific condition or characteristic is found; "a belt of high pressure" ...
Britney E. Schmidt, a UCLA doctoral student, led a team of researchers to create a 3D model of the 600km-wide rock which lies within the main asteroid belt between the orbits of Jupiter and Mars. With the Hubble images, Schmidt and her colleagues were able to take new measurements of Pa...
or it could be a planet-crossing asteroid being ejected from the solar system after a close encounter with a planet, most likely Jupiter. Again, objects on some planet-crossing orbits may have originated in either the Kuiper belt or the main asteroid belt. Unless such an object reveals itself...
7The Asteroid Belt The asteroid belt currently contains only enough material to make a planet 2000 times less massive than Earth, even though the spatial extent of the belt is huge. It seems likely that this region once contained much more mass than it does today. A smooth interpolation of ...
A region between Mars and Jupiter became the asteroid belt. Occasionally people wonder whether the belt was made up of the remains of a destroyed planet, or a world that didn't quite get started. However, according to NASA, the total mass of the belt is less than the moon, far too ...
Originally, the Asteroid Belt was thought to be the remnants of a much larger planet that occupied the region between the orbits of Mars and Jupiter. This theory was originally suggested by Heinrich Olbders to William Herschel as a possible explanation for the existence of Ceres and Pallas. How...
The largest object in the asteroid belt is Ceres, a dwarf planet, which makes up roughly one third of the total mass of the asteroid belt. Giuseppe Piazzi discovered Ceres and named it after the Roman goddess of agriculture.The first spacecraft to go through the asteroid belt was Pioneer ...
