433 Eros
The asteroid 433 Eros (eer'-os) was named after the Greek god of love Eros. It is an S-type asteroid approximately 13 Ã- 13 Ã- 33 km in size, the second-largest near-Earth asteroid, belonging to the Amors.

Eros
A small asteroid, No. 433 (axes 35 × 16 × 17 km) whose closest approach to Earth is less than 0.15 AU. Rotation period 5h16m12s.913, orbital period 642 days, a = 1.48 AU, e = 0.223, i = 10°.8; perihelion distance 1.084 AU. Discovered by G.
Why Eros?
Basically, because it's big and close. Asteroid 433 Eros is one of the largest near-Earth asteroids, with a mass thousands of times greater than similar asteroids.
Eros, Asteroid #433, is an elongated Near-Earth Asteroid which is 21 by 8 by 8 miles (33 by 13 by 13 kilometers). The density of Eros is 2.4 grams per cubic centimeter, roughly the same as the density of Earth's crust.
Eros, was the first asteroid to have a spacecraft put in orbit around it. Given its size and location, it is not a likely candidate to have life on it.
EROS
Eros, Asteroid #433, is a Near-Earth Asteroid (NEA). This elongated asteroid is 21 by 8 by 8 miles (33 by 13 by 13 kilometers). The force of gravity on Eros is 1000 times weaker than the gravity on Earth; it has no atmosphere.

The near-Earth asteroid Eros is made of material that has not been much altered since its accretion from the circum-Solar dust disk 4.
Asteroid Eros from NEAR-Shoemaker in orbit
Asteroids are thought to be the remnants of a stillborn planet.
On reaching Eros in February 1999, NEAR will go into orbit around it, coming as close as 24 km to the surface.
The first asteroid to be given a masculine name, Eros (number 443) was the first to be discovered inside the orbit of Mars. The Trojan asteroids, named for heroes of the Trojan war, are in the orbit of Jupiter. astral dome = astrodome.
Earth Resources Observation Systems (Global Land Information System Glossary - USGS) The Earth Resources Observation Systems (EROS) program was established in the early 1970s, under the Department of the Interior's U.S.
The measures were made with the Cape heliometer and have never been superseded, for the latest results with the minor planet Eros exactly confirm Gill's result-8.80" - while they decidedly diminish the associated probable error.
These - such as MACHO, OGLE, EROS, AGAPE, MOA - use stars in the LMC or galactic bulge (for AGAPE, in M31 via what's known as pixel lensing) as background sources and watch for the characteristic shape of a lensing event as foreground point sources ...
then, increasingly distant planets have been reached, with probes landing on or impacting the surfaces of Venus in 1966 (Venera 3), Mars in 1971 (Mars 3, although a fully successful landing didn't occur until Viking 1 in 1976), the asteroid 433 Eros ...
Aphrodite and her son Eros took cover among the reeds on the banks of the Euphrates, but when the wind rustled the undergrowth Aphrodite became fearful. Holding Eros in her lap she called for help to the water nymphs and leapt into the river.
Launched on February 17, 1996, this probe (Catalogue No. 433), renamed for Eugene Shoemaker, arrived at Eros on the 14th of that same month in 2000.
The spacecraft carried instruments, including a multi-Spectral Imager (MSI) used to determine Eros's shape and surface features, and mineral distributions.
It was launched on February 17, 1996; its goal was to rendezvous with asteroid 433 Eros (pictured above). In 2001, NASA renamed the spacecraft NEAR Shoemaker to honor the planetary science pioneer Dr. Eugene M. Shoemaker, who died in 1997.

On February 14, 2000 the NEAR spacecraft went into orbit about the asteroid Eros. It thoroughly mapped and scanned the surface of Eros from that time until February 2001.

Minor planets, also called asteroids, are rocky objects in orbit around the sun.
As for Aphrodite and Eros, who escaped the monster's wrath, these two were given their fish-like images in the heavens, thus commemorating the time Typhon nearly overran Olympus.
Eros from the NEAR sattellite
The study of asteroids is one important key to the understanding of the early solar system.
The most extensive study of any minor body to date was provided by NEAR-Shoemaker, which entered orbit around the asteroid Eros on February 14, 2000.
Primary scientific objectives were to return data on the bulk properties, composition, mineralogy, morphology, internal mass distribution, and magnetic field of 433 Eros as the spacecraft orbited the asteroid from February 14, 2000 to February 12, ...
Among those, special interest is attached to "Earth-crossing" asteroids whose orbit approaches the Sun closer that Earth--such as "Eros" pictured here, an image from NASA's "NEAR" mission taken 15 December 2000.
The fish are the goddess Aphrodite and her son Eros (Roman: Venus and Cupid). They turned themselves into fish in order to escape from the monster Typhon. They then connected themselves together with a ribbon in order not to be separated.
She was the mother of Eros (Cupid), Deimus (Fear), Phobus (Panic) and Harmonia, wife of Cadmus. One of her mortal son, was Aeneas, by her lover was Anchises, king of Dardania.
In June 1997, NEAR (Near Earth Asteroid Rendezvous) passed by 253 Mathilde on its way to a year 2000 Valentine's Day encounter with 433 Eros, an Earth-grazing asteroid and the first one discovered to come inside the orbit of Mars.
In Greek mythology, the constellation Pisces is associated with the fish into which the goddess Aphrodite and her son Eros transformed in the Euphrates while fleeing from the monster Typhon.
In Greek mythology, the two fish represent Aphrodite and her son, Eros. One day they were fleeing the giant Typhon, when they jumped into a stream, turned to fish and swam away. It is said they tied a string to their tails so they could stay together.
"Asteroids seen up close, like Ida, Mathilde, and Eros, and the small martian satellites do not have the bright 'speckling' associated with the small craters that are seen on Phoebe," explained Dr. Peter Thomas.
The discovery of the near-Earth asteroid 433 Eros and its passage near the Earth in 1900-1901 allowed a considerable improvement in parallax measurement.
The Amor asteroids are a class of with -crossing orbits. Eros is one of the larger Amors, and NASA's Near-Earth Asteroid Rendezvous (NEAR) mission, launched Feb. 17, 1996, is scheduled to visit it in Jan. or Feb. 1999. There are 231 known Amors ( ).
Mathilde is a dark C-type (brightness enhanced several times to match the other three). Gaspra, Ida, and Eros are S-type asteroids. Mathilde and Eros were visited by NEAR Shoemaker and Gaspra and Ida were visited by Galileo.
Its shape is apparently as elongated as that of Eros. Rotation period 6.9225 hours. Its visual mean opposition magnitude is near +14.5, which makes it the brightest of the Trojans. Assumed albedo 0.28. It has a large obliquity. [H76]

The X-ray/gamma-ray spectrometer (XGRS), one of five major facility instruments on the NEAR spacecraft, is the primary experiment for determining surface/near-surface elemental composition of the near-Earth asteroid 433 Eros.
One of the largest inner asteroids is Eros, an elongated body measuring 36 by 12 km (22 by 7 mi). The peculiar Apollo asteroid Phaethon, about 5 km (about 3 mi) wide, approaches the sun more closely, at 20.
It is made up of thousands of objects too small to be considered planets. Some of them no larger than a grain of dust, while others, like Eros can be more than 100 miles across. A few, like Ida, even have their own moons.
9 M⊙ could add more than 20% to the known mass discrepancy in the Galaxy halo. If there is a baryonic component to Dark Matter it appears to be quite small. This result is supported by other microlensing programs such as OGLE and EROS.
