Latest Near-Earth object Stories
On March 10, 2013, NASA scientists obtained a sequence of radar images of asteroid 2013 ET using the 230-foot Deep Space Network antenna at Goldstone, California.
An asteroid about the size of a city block will be making its way past Earth this afternoon, and Slooh plans on giving the world access to its tools to view the near-Earth object (NEO).
An asteroid that was only discovered Saturday (Mar. 2) has made a run by Earth in the early hours of March 5, some 250,000 miles away. While the asteroid is being associated with last month’s Russian meteor in respect to its mass, the two bodies are not linked in any other way.
Initial reports put last Friday’s (Feb 15) Chebarkul meteorite that exploded over Russia’s Urals region at about 10 tons. But after careful analysis, NASA released new information that puts the meteorite closer to 10,000 tons—1,000 times larger than the estimates size reported by the Russian Academy of Sciences.
An initial sequence of radar images of asteroid 2012 DA14 was obtained on the night of Feb. 15/16, 2013, by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif. Each of the 72 frames required 320 seconds of data collection by the Goldstone radar.
The first firm details of the 15 February asteroid impact in Russia, the largest in more than a century, are becoming clear.
On February 15, asteroid 2012 DA14 passed extraordinarily close to the earth.
As reports continue to stream in through various media outlets on injuries, damages, and the science behind such events, it seems this morning’s (February 15) meteor strike in Russia’s Ural Mountains region has left a pretty big impression far and wide.
A meteor streaked across Russia’s early morning skies on Friday before violently exploding, sending a rain of debris onto the Earth below. The flash and boom shattered windows and meteor particles left damage in its wake, injuring more than 900 people in the Ural Mountains region.
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 Î”V (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 Î”V 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...
