1015 kilograms, which is a bit even for an asteroid. It is an S-type asteroid about 13 13 33 km in size, the second-biggest near-Earth asteroid (NEA) after 1036 Ganymed.It belongs to the Amors.It is the first asteroid that was known to cross inside the orbit of Mars.Eros is one of the few NEAs bigger than 10 km . The first mission to orbit a near-Earth asteroid was the NEAR Shoemaker mission to the asteroid Eros in the year 2000. And now, seven years later, it is doing so again: on this coming Tuesday, January 15, it passes . The eccentricity of the orbit of Eros is e=0.223. It was visited by NASA's Near Earth Asteroid Rendezvous in 2000. Diameter: 8.48 km. Eros is an S-type near-Earth asteroid approximately 34.4 11.2 11.2 kilometers in size, the second-largest near-Earth asteroid after 1036 Ganymed. It was visited by NASA's Near Earth Asteroid Rendezvous in 2000. 1 P = 1 P E 1 P Eros = 1 365 1 847 P= 625 days= 1:71yr P2 = Ka3 a= 3 r . The Near Earth Asteroid Rendezvous (NEAR) mission (later renamed NEAR Shoemaker) reached 433 Eros in 2000, and one of the exciting results was the discovery of features called "ponds". At its closest, it was be about 16.6 million miles (26.7 million km) away . However, if we take into account the size of the asteroid - 34.4 km in diameter in the widest place - it turns out that Eros is quite dense, about 2.67 g / cm. The distance of Asteroid 433 Eros from Earth is currently 315,341,679 kilometers, equivalent to 2.107929 Astronomical Units . Here we report a study of the dynamical evolution of Eros's orbit over a period of two million years. The eccentricity of the orbit of Eros is e=0.223. It became the first spacecraft to enter orbit around an asteroid, doing so at the large near-Earth asteroid 433 Eros in February 2000. NEAR Shoemaker2 embarked on its journey to the near-Earth asteroid 433 Eros on 17 February 1996 when the spacecraft was successfully launched by a Delta-2 rocket. Distance Kilometers 299,958,308. Distance AU -0.120239. 433 Eros is the first Near-Earth asteroid (NEA) that was found. The Near-Earth Asteroid Rendezvous (NEAR) mission spent about a year orbiting the asteroid 433 Eros, a 33 x 13 x 13 km chunk of rock.The main goal of the mission was to determine the chemical and mineral make up of the asteroid and to try to settle an argument about the nature of S-asteroids. During its encounter with 253 Mathilde, the spacecraft photographed 60 percent of the minor planet from a distance of 750 miles (1,200 km). This makes Eros about twice as dense as asteroid 253 Mathilde, a C-type, carbon-rich asteroid that NEAR flew past in June 1997, and about the same density as S-type asteroid 243 Ida, which NASA . A member of a group called near-Earth, or Earth-approaching, asteroids, Eros can pass within 22 million km (14 million miles) of Earth.During a close approach in the 1930s (before the development of direct radar ranging), astronomers were able to observe the asteroid's parallax displacement against the background stars to refine their measurement of Earth's mean distance from the Sun, the . Even though Eros will come no closer than about 17 million miles, it will show a perceptible (and measurable) position difference from place to place. What is the length a of the semimajor axis of Eros orbit? On Jan. 31, 2012, it made its closest approach to Earth, passing only 16.6 million miles (26.7 km) from the planet, or 20 times the distance to the moon. It is an S-type asteroid about 13 13 33 km in size, the second-biggest near-Earth asteroid (NEA) after 1036 Ganymed.It belongs to the Amors.It is the first asteroid that was known to cross inside the orbit of Mars.Eros is one of the few NEAs bigger than 10 km . Eros was the first near-Earth asteroid to be discovered, turning up accidentally on a photograhic plate in 1898. It belongs to the Amor group. The NEAR spacecraft first flew by Eros on Dec. 23, 1998, at a distance of about 2,400 miles (about 3,800 kilometers) and found that the asteroid was smaller than expected and had two medium-sized craters, a long surface ridge, and a density similar to that of Earth's crust. Between January 1970 and January 1970 the closest approach of Asteroid (NEO) 2021 WU to Earth happens on Thu Jan 1 1970 at a distance of -0.12023933 Astronomical Units, or -17,987,547 kilometers: Date Thu Jan 1 1970. However, astronomers have an unusual definition of "near", due to the incredibly vast distances in space. 433 Eros is the first Near-Earth asteroid (NEA) that was found. Between January 1970 and January 1970 the closest approach of Asteroid (NEO) 2021 WP2 to Earth happens on Thu Jan 1 1970 at a distance of -0.12023933 Astronomical Units, or -17,987,547 kilometers: Date Thu Jan 1 1970. NEAR's road to Eros 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). Discovered in 1898, Eros is one of the larger near-Earth asteroids, at only 20 miles (33 kilometers) wide. A massive asteroid stronger than a nuclear bomb will swoosh past the Earth in late December, according to NASA's asteroid tracker. The approaches of the asteroid Eros. Discovered in 1898, Eros is one of the larger near-Earth asteroids, at only 20 miles (33 kilometers) wide. Eros, an asteroid composed by magnesium and iron silicate, was discovered on August 13, 1898 by astronomers Carl Gustav Witt and Auguste Charlois. (NEAR-Shoemaker was not designed for a landing, so the successful touchdown provided . The following chart shows the distance of Asteroid (NEO) 2021 WJ1 from Earth as a function of time. It made the first reconnaissance of a C-type asteroid during its flyby of the main-belt asteroid 253 Mathilde in June 1997. It was the first asteroid orbited by an Earth probe (in 2000). It's a Mars-crosser asteroid, which means it comes within the orbit of Mars. It was the first spacecraft to orbit an asteroid and eventually landed successfully on the asteroid Eros in 2001. 951 Gaspra - Imaged by Galileo on 29 Oct 1991. Close Approaches. When . 1566 Icarus - Highly eccentric Earth-crossing orbit. The NEAR Shoemaker spacecraft caught up with asteroid Eros in February 2000 and orbited the small body .
