Small Asteroid Will Safely Pass Earth
2014-03-06 12:52:56

NASA's Jet Propulsion Laboratory An asteroid about 25 feet (8 meters) across will safely pass Earth at about 1:21 p.m. PST (4:21 p.m. EST) today, March 6, approaching us six times closer than the moon. This distance, though not unusual, is closer than the Earth flyby of a larger asteroid on Wednesday afternoon, March 5. This afternoon's flyby object, asteroid 2014 EC, was discovered on March 5 by the Catalina Sky Survey near Tucson, Ariz. Its closest-approach distance, about 38,300...

Large Asteroid Set To Pass Between Earth And Moon
2014-03-04 14:50:08

Lee Rannals for redOrbit.com - Your Universe Online An asteroid with a diameter about the size of an 80-story building is sweeping by Earth and the moon on Wednesday. Asteroid 2014 CU13 was first discovered on February 11th by Mt. Lemmon Survey. Since then, the asteroid has been viewed over 230 times, but there still remains a lack of information in trying to pinpoint the space rock’s exact orbit. Slooh will be attempting to offer up a webcast of the asteroid as it makes its...

[ Watch the Video: What's So Weird About A New Comet? ] DC Agle, NASA Jet Propulsion Laboratory NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft has spotted a never-before-seen comet - its first such discovery since coming out of hibernation late last year. "We are so pleased to have discovered this frozen visitor from the outermost reaches of our solar system," said Amy Mainzer, the mission's principal investigator from NASA's Jet Propulsion...

[ Watch the Video: NASA Spots New Near-Earth Asteroid ] DC Agle, NASA Jet Propulsion Laboratory A collage of radar images of near-Earth asteroid 2006 DP14 was generated by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif., on the night of Feb. 11, 2014. Delay-Doppler radar imaging revealed that the asteroid is about 1,300 feet (400 meters) long, 660 feet (200 meters) wide, and shaped somewhat like a big peanut. The asteroid's period of...

Large Asteroid Passes Within A Few Million Miles Of Earth
2014-02-18 11:05:41

Lee Rannals for redOrbit.com - Your Universe Online 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 exploded over Russia. The asteroid, which was estimated to be about the size of three football fields, whizzed by Earth last night at a distance of 2.1 million miles and traveling at about 27,000 mph. Slooh provided a broadcast of the event so online spectators...

Responding To Potential Asteroid Redirect Mission Targets
2014-02-15 06:26:56

NASA/Jet Propulsion Laboratory One year ago, on Feb. 15, 2013, the world was witness to the dangers presented by near-Earth Objects (NEOs) when a relatively small asteroid entered Earth's atmosphere, exploding over Chelyabinsk, Russia, and releasing more energy than a large atomic bomb. 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. NASA is now pursuing new...

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...
