	ASTEROID,
		The first asteroid found to have a moon was the main-belt asteroid Ida, whose satellite, given the name Dactyl, was discovered by the U.S. Jupiter-bound space probe Galileo in 1993.
		Asteroids that cross the orbit of Mars or whose orbit lies entirely within that of Mars are called near-earth asteroids.
		The Aten asteroids, of which a couple of hundred are known, also may cross earth's orbit, but they do so near their furthest point from the sun (aphelion); the few whose orbit lies entirely within earth's are called Apohele asteroids.

		Eos asteroids have a semi-major axis between 2.99 AU and 3.03 AU, an eccentricity between 0.01 and 0.13, and an inclination between 8° and 12°.
		Alinda asteroids have a mean orbital radius of 2.5 AU and an eccentricity between 0.4 and 0.65 (approximately).
		Trojan asteroids have a mean orbital radius between 5.05 AU and 5.4 AU, and lie in elongated, curved regions around the two Lagrangian points 60° ahead and behind of Jupiter.

	Apohele asteroid
		They have not only their perihelion at less than one AU (within Earth's orbit), but also their aphelion; that is, their entire orbit is within Earth's.
		As of July 2004 there are only two confirmed Apoheles: 2003 CP and 2004 JG An earlier object, 1998 DK, has not been seen since February 24 1998 and its discoverer David J. Tholen acknowledges that it is currently lost.
		The name Apohele is still under a bit of debate, since most asteroid subclasses are named for prominent members of that group (for example, Aten asteroids are named for 2062 Aten, the first such asteroid discovered), whereas there is no asteroid named "Apohele".

	Chapter 20: Meteorites and Asteroids
		There is other independent evidence for an asteroid impact at Chicxulub, the team said, including the purported find of an asteroid fragment in an oceanic drill core, the amount of iridium spread around the world at the time of impact, and a telltale chromium 53 isotopic signature.
		The asteroid belt is the source for a smaller group of asteroids called "near- earth objects," which have broken from the belt and have the potential to collide with earth.
		The new HST measurements indicate that the asteroid is slightly flattened, with a diameter ranging from 930 to 970 kilometers.

	apohele
		An asteroid whose orbit lies entirely inside that of Earth.
		Apoheles form a subgroup of the Aten group.
		In addition, the 40-m-wide object 1998 DK36, discovered by Tholen and Robert Whiteley in February 1998, may have been an apohele but it was observed on only two consecutive days and subsequently lost due to failure of the observing instrument.

	Pravda.RU:Asteroid hints at the smallest orbit (Site not responding. Last check: 2007-10-20)
		Such asteroids are very difficult to detect because their position in relation to the Sun and the Earth means they rarely appear in the night sky.
		According to spaceref.com asteroids with orbits entirely within the Earth's orbit have been informally called "Apoheles," from the Hawaiian word for orbit.
		There may exist about 50 Apoheles of comparable size to or larger than 2004 JG6, but many of them are certain to be unobservable from the ground.

		[1] These three asteroids have aphelia in the 0.980-0.973 AU range.
		In great part because of the search methods used to look for asteroids, there are currently no known asteroids with orbits contained within Venus' or Mercury's (e.g., Vulcanoids).
		The name Apohele is still under a bit of debate, since most asteroid subclasses are named for prominent members of that group (for example, Aten asteroids are named for 2062 Aten, the first such asteroid discovered), whereas there is no asteroid named "Apohele".

		Ordinary asteroids are located between the orbits of Mars and Jupiter, roughly two to four times farther from the Sun than Earth, taking several years to go around the Sun.
		Because of the near-exact six-month period, the asteroid should be observable again in nearly the same spot in the sky next May, having gone around the Sun twice while Earth will have made only one circuit.

	ATEN ASTEROID FACTS AND INFORMATION
		The Aten asteroids are a group of near-Earth_asteroids, named after the first of the group to be discovered (2062_Aten, discovered January_7 1976 by Eleanor_F._Helin).
		Nearly all known Aten asteroids have their aphelion greater than one AU.
		For a brief time near the end of 2004, the asteroid 99942_Apophis (then known only by its provisional_designation) appeared to pose a threat of causing an Earth impact_event in 2029, but earlier observations were found that eliminated that possibility, although a very small possibility still exists for the years 2035 and 2036.

	Minor planet groups/families
		The following is an updated version of a list of asteroid groups and families that I posted on the Minor Planet Mailing List.
		Families are different and result from the catastrophic breakup of a large parent asteroid sometime in the past.
		The Minor Planet Center holds that the name for a group comes from the first asteroid in that group to be named (except for those in the Trojan and more distant groups.) So far, we aren't even close to having a named object for these groups, or even one that is unambiguously in the group.

		It is located at about the inner edge of the zone, while 1989 VA, the first asteroid discovered there, is at about the outer edge.

		1998 DK (also written 1998 DK36) is possibly the first Apohele asteroid (asteroid that is always closer to the Sun than Earth) detected.
		It was discovered by David J. Tholen, but is now considered lost and does not appear in authoritative catalogs.
		While its orbital elements have not been well established, its aphelion (farthest distance from Sun) was determined to be less than the Earth's distance to the Sun.

		A fortuitous recent result of asteroidal spectrography found that the object under observation was, in fact, a nearly dormant comet.
		For one thing, the WISE science page states that it "will be able to measure the diameters of more than 100,000 asteroids," but this is only a small fraction of the total main-belt population, which is in the range of 1.1-1.9 million, and that's just the ones more than a kilometer in diameter.
		It will be better at detecting smaller asteroids closer to Earth, but any such observation must be completed by ground-based observers, who face the limitations of sensitivity, moonlight, and declination already mentioned; the spacecraft's survey program does not allow follow-up exposures for orbit determination.
