	Vulcanoid asteroid - One Language (Site not responding. Last check: 2007-09-10)
		Vulcanoids are hypothetical asteroids that may orbit in a dynamically stable zone between 0.08 and 0.21 astronomical units from the Sun, well within the orbit of Mercury.
		Nevertheless, it is thought Vulcanoids could exist because the region of space being searched is gravitationally stable, and all similarly stable regions of the solar system have been found to contain objects.
		Vulcanoid asteroids, if they exist, would be a special subclass of Apohele asteroids.

		Asteroids with known orbits are listed in a catalog giving their order of discovery and, when possible, the name they have been given by their discoverer.
		The IRAS data seemed to show that the biggest asteroids have a different range of albedos than the smaller ones, which may be due to the fact that a high proportion of smaller asteroids may be fragments from the cores of larger parent bodies.
		Asteroids in the inner regions of the main belt, closest to the Sun, appear to be predominantly stony-metallic.

		Vulcanoids would need to be in near-circular orbits, each avoiding the others, if they were to have survived the billions of years since the solar system formed.
		But it seems to be an impossible task: the vulcanoids would need to be larger than about 20km, dependent on their reflectivities, to be detectable from a mountaintop observatory.
		No vulcanoids have been detected, but that in itself is a useful result, allowing limits to be placed on how many exist.

		The Vulcanoids are a hypothetical population - an asteroid belt, if you will - inside the orbit of Mercury, which may or may not exist.
		We require that the object be moving at just the right rate and direction predicted by what a Vulcanoid orbit would be and that it not be one of the known stars or asteroids.

		Most of these are very small and irregular asteroids, and with a few exceptions, are generally ignored by astrologers, but the larger and more spherical ones are being closely studied and even incorporated into chart interpretation.
		Vulcanoid asteroids, for example, are presumably located within the orbit of Mercury, close to the Sun, although none have yet been ascertained.
		It is somewhere between an asteroid and a comet, and despite its small size(some 100-150 miles in diameter) it seems to have taken on important astrological significance, probably due to its strategic location between Saturn and Uranus at an average of 13.7 AU.

		The strength-scaling law, which describes the strength of asteroids as a function of their size, was shown to dominate the evolution of the main-belt size distribution--the power law used to describe fragmentation and the initial starting population have a minimal effect on the final population.
		While the evolved population of asteroids in the model is consistent with observations of large asteroids, the resulting population of bodies smaller than 3 km in diameter is insufficient to explain the cratering records observed on Ida and Gaspra by the Galileo spacecraft [2,3].
		Assuming Kuiper Belt objects have a mean density 1/2 that of asteroids and that the mean relative velocity in the Kuiper Belt is 1/3rd that in the main-belt, a 2.6 km Kuiper Belt object delivers the same energy to a target as a 1.0 km object in the main-belt.
