	Encyclopedia: 433 Eros
		Eros was visited by the NEAR Shoemaker probe, which orbited it, taking extensive photographs of its surface, and then, on February 12, 2001 at the end of its mission, landed on the asteroid's surface using only its maneuvering jets.
		Eros exhibits a heavily cratered surface with one side dominated by a huge, scallop-rimmed gouge, and the opposite side by a conspicuous sharp, raised rimmed crater.
		This montage shows a selection of images of the asteroid 433 Eros that were acquired from the NEAR spacecraft over three weeks from January 22 through February 12, 2000, as the spacecraft's distance from its target shrank from 18,000 to 1260 miles (29,000 to 2025 km).

		The surface gravity on Eros varies a lot, since it is not a sphere but an elongated peanut-shaped (or potato- or shoe-shaped) object.
		NEAR scientists have found that most of the larger rocks strewn across Eros were ejected from a single crater in a meteorite collision perhaps 1 Ga (1 billion (The number that is represented as a one followed by 9 zeros) years) ago.
		Eros is claimed as property by Gregory W. Nemitz of OrbDev.

	433 Eros
		Eros is one of the S-type (silicaceous) asteroids, the most common type in the inner asteroid belt and the subject of debate over their relationship to meteorites.
		This montage of images of the asteroid Eros was assembled from images acquired by the Near Earth Asteroid Rendezvous (NEAR) spacecraft on December 23, 1998, as the spacecraft flew by the asteroid at a distance of 3800 kilometers at 1:43 PM EST.
		This pair of images of the asteroid Eros was acquired by the Near Earth Asteroid Rendezvous (NEAR) spacecraft on December 23, 1998, as the spacecraft flew by the night side of the asteroid at a distance of 3800 kilometers at 1:43 PM EST.

	Shape of Asteroid 433 Eros
		Asteroid 433 Eros is the second largest member of the near-Earth population and also one of the most elongated.
		Eros' elongation is also evident in 3.5-cm Goldstone radar echoes (Jurgens and Goldstein 1976); as the asteroid rotates, the echo's Doppler bandwidth varies by about a factor of two.
		Eros could be an intact fragment from a (highly or slightly) differentiated parent body, in which case mineralogical variations in that body might be preserved in Eros.

	433 Eros
		433 Eros is an S-type asteroid orbiting the Sun mostly between the orbits of Earth and Mars.
		Eros might be a fragment from a planetoid that coalesced long ago and later broke apart as a result of collisions with other asteroids.
		Inside Eros' Giant Gouge This picture was taken from NEAR on February 15, 2000, while the spacecraft was passing directly over the large gouge that creates Eros's characteristic peanut shape.

	433 Eros - Wikipedia, the free encyclopedia
		Since Eros is irregularly shaped, a 9 kilometer straight line through the asteroid can reach locations that would be further away if travelling across the surface, thus leading to the uneven pattern of crater density on the surface.
		In an experimental legal case, Eros was claimed as property by Gregory W. Nemitz of OrbDev.
		According to the Homestead principle, Nemitz argued that he had the right to claim ownership of any celestial body that he made use of; he claimed he had designated Eros a spacecraft parking facility and wished to charge NASA a parking and storage fee of 20 cents per year for NEAR Shoemaker.

	The Mythology of Eros (Site not responding. Last check: 2007-09-05)
		Eros flies over the earth and over the loud-roaring salt sea and bewitches the one on whose frenzied mind he darts, winged and gold-gleaming, he bewitches the whelps of the mountain and those of the sea, what the earth brings forth and what the blazing sun looks down upon, and likewise mortal men.
		Eros, concerned by her condition, finally agrees to allow Psyche’s sister to visit, but he warns her again not to gaze upon his face.
		The Eros she knows now is…produced by the Soul’s contemplation of the Divine Mind; it is the medium through which she can finally be present to "that other loveliness".

	(433) Eros (Site not responding. Last check: 2007-09-05)
		(433) Eros was the first Mars-crossing asteroid to be discovered and the first known asteroid that could make a close approach to the Earth.
		The asteroid was studied by the NEAR-Shoemaker probe in 2001 and a huge amount of high-quality data was obtained, including extreme close-up images of the surface obtained during the remarkable soft landing of the probe on the surface on February 12th 2001.
		Eros is classified as an Amor asteroid - one that has its perihelion between the orbit of the Earth and Mars.

		Eros is moving among constellations of the Zodiac -- moving from Aquarius into Pisces in February.
		You'll be able to see Eros through a back-yard telescope during favorable months but you will never be able to see the small, Volkswagen-beetle-sized spacecraft through a telescope, however, because it will be too far away and too close to Eros to see separately.

	Application to 433 Eros
		Eros has many of the same distinguishing characteristics as Geographos (and our B- and M-class remnant rubble piles).
		Regardless of whether Eros is covered by regolith or bare rock, spectroscopic measurements will suggest a surface composition which can be directly compared to terrestrial rock samples.
		Thus, the presence of a small moon about Eros would be a strong indication that it had undergone tidal fission.

	One Crater On 433 Eros Source Of Most Ejected Rocks
		Eros is estimated to be about 4 billion years old, probably the remnant of a larger asteroid broken up by a collision with another asteroid.
		Perhaps a billion years ago, Eros itself was struck by an object -- a meteorite or small comet -- creating a crater nearly 5 miles (7.6 kilometers) wide and shattering into rocks of all sizes.
		The mystery posed by the Eros maps for the researchers is why the same thing didn't happen with two other large craters on Eros: Himeros, on the body's convex side, and Psyche, on the concave side.

	NEAR and asteroid 433 Eros
		However, it is already clear that Eros does not have a high density of giant craters as found on Mathilde, where the giant craters approach geometric saturation (by giant craters we mean those that have a diameter close to or bigger than the radius of Mathilde itself).
		NEAR is cruising toward 433 Eros for tomorrow's historic rendezvous with the asteroid.
		The 'heart of Eros' is actually a 5 km long depression in the surface, and it appears as a heart because of an accidental confluence of shadows.

	PSRD: Asteroid Porosity
		They compared this estimate with features seen on the surface of Eros and with previously proposed models for the formation of asteroids to conclude that Eros has been heavily fractured by impact collisions but was not demolished to the extent that it is now a rubble pile.
		Some early predictions placed Eros in the "reassembled rubble-pile" model wherein the asteroid is a pile of gravitationally bound fragments from earlier catastrophic smashes.

	SVS Science Story: A Virtual Eros -- Take a 3-D Spin Around 433 Eros
		The model can then be used to generate a virtual tour of the asteroid 433 Eros.
		The NLR measures heights on Eros' surface by determining the time short pulses of laser light take to travel from the spacecraft to the asteroid and back.
		The elevations of points on the surface of Eros are determined by subtracting the laser-derived distance between the spacecraft and the surface from the distance between the spacecraft and Eros' center of mass, as determined from radio tracking.

	A VIRTUAL EROS -- TAKE A 3-D SPIN AROUND 433 EROS
		The asteroid's shape, density and spin combine to create a bizarre pattern of what is "uphill" and "downhill." In this view, a map of "gravity slope" has been painted onto the topographic model generated by the NEAR Laser Rangefinder (NLR).
		The chief goal of the controlled descent to the surface is to gather close-up pictures of the boulder-strewn surface of 433 Eros, more than 196 million miles from Earth.
		The primary goal of the controlled descent is to get the closest images yet of Eros, particularly its "saddle" area, a 6-mile wide depression that has intrigued scientists with its boulder patches, relatively craterless surface and patterns of grooves and ridges.

		This ellipsoid fits the observed shape of Eros as described to NLR190 to 1028 in an RMS sense.
		This is not a very good fit due to the fact that Eros deviates significantly from a simple ellipsoidal shape.
		Results suggest that the major axis is approximately 11° away from the X-axis of the coordinate system and the "polar" axis (b) is about 8° from the Z-axis.
