Latest Near-Earth object Stories
The Earth faced a “close-call” on Monday night as near-Earth asteroid 2000 EM26 came within a couple million miles of the planet, nearly a year after the Chelyabinsk meteor slammed into Russia.
Tracking near-Earth asteroids has been a significant endeavor for NASA and the broader astronomical community, which has discovered 10,713 known near-Earth objects to date.
In June of last year, NASA Administrator Charlie Bolden spoke to the United Nations Committee on Peaceful Uses of Outer Space (COPUOS) and shared with the international community what NASA is doing to detect and track asteroids.
Astronomers, using the European Southern Observatory’s (ESO) New Technology Telescope (NTT), have discovered that asteroids have a highly varied internal structure.
For the first time, national space agencies from Africa, Europe, the Americas and Asia will establish an expert group aimed at getting the world’s space-faring nations on the ‘same page’ when it comes to reacting to asteroid threats.
Once a hibernating craft drifting silently through space, NEOWISE was repurposed and reactivated last month with a new mission – find asteroids and other potentially hazardous near-Earth objects.
NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) has made its first discovery since coming out of hibernation last year: a never-before-seen asteroid dubbed 2013 YP139.
According to NASA, the first asteroid of the 2014 season was discovered by Catalina Sky Survey, a NASA-sponsored observatory near Tucson, Arizona. It has been designated as 2014 AA and was viewed moving across the sky early Wednesday morning, January 1, 2014.
NEOWISE has returned to service, and has sent its first set of test images back to Earth in preparation for a renewed mission.
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...
