2013-10-18 12:02:43

Astronomers working at the Crimean Astrophysical Observatory in Ukraine found a new asteroid on October 13, 2013 and NASA confirmed it came within about 4.2 million miles of Earth on September 16. New estimates predicts a slight chance of impact in 2032.

Asteroid Don Quixote Is Actually A Comet
2013-09-11 04:25:30

When is a near-Earth asteroid not a near-Earth asteroid? When an international team of researchers discover that the object has been misidentified by the scientific community for the past three decades, and is actually a comet.

Close To One Hundred Ideas Selected For Possible NASA Asteroid Missions
2013-09-04 13:25:34

NASA has selected 96 asteroid initiative ideas about how to protect Earth from asteroids and find a space rock for humans to explore. The list was dwindled down from more than 400 submissions the space agency received since June.

NEAR-Shoemaker Mission -- The Near Earth Asteroid Rendezvous - Shoemaker (NEAR Shoemaker), renamed after its launch in honor of Gene Shoemaker, is an unmanned spacecraft designed to study the near-Earth asteroid Eros from close orbit over a period of a year. The primary scientific objectives of NEAR were to return data on the bulk properties, composition, mineralogy, morphology, internal mass distribution and magnetic field of Eros. Secondary objectives include studies of regolith...

Near-Earth Object -- Near-Earth Objects (NEO) are asteroids, comets and large meteoroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger. Due to their size and proximity, NEO's are also more easily accessible for spacecraft from Earth and are important for future scientific investigation and commercial development. In fact, some near-Earth asteroids can be reached with much less ΔV (change in velocity) than the Moon. In the United States, NASA...

Near-Earth Asteroid -- Near-Earth asteroids (NEAs) are asteroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger, as well as being most easily accessible for spacecraft from Earth. In fact, some near-Earth asteroids can be reached with much less ΔV than the Moon. The most famous near-Earth asteroid is 433 Eros that was visited by NASA's Near Earth Asteroid Rendezvous probe. A few hundred such near-Earth asteroids are known, ranging in size up...

433 Eros -- The asteroid 433 Eros was named after the Greek god of love Eros. It is an S-type asteroid approximately 13 x 13 x 33 km in size, the second-largest near-Earth asteroid. It was visited by the NEAR Shoemaker probe, which first orbited it taking extensive photographs of its surface and then in 2001 at the end of its mission was landed on the asteroid's surface using only its maneuvering jets. Depending on where they stood on Eros, a person who weighed 200 pounds (90...
