NASA A small asteroid, designated 2014 RC, will safely pass very close to Earth on Sunday, Sept. 7, 2014.  At the time of closest approach, based on current calculations to be about 2:18 p.m. EDT (11:18 a.m. PDT / 18:18 UTC), the asteroid will be roughly over New Zealand.  From its reflected brightness, astronomers estimate that the asteroid is about 60 feet (20 meters) in size. Asteroid 2014 RC was initially discovered on the night of August 31 by the Catalina Sky Survey near Tucson,...

NASA NASA is finding asteroids, including those that might threaten our home planet, and sending humans to explore one. The agency is engaging the public in the Asteroid Grand Challenge to find all asteroid threats to human population and know what to do about them, accelerating NASA's existing planetary defense work. NASA is also developing a first-ever mission to identify, capture and redirect a near-Earth asteroid to a stable orbit around the moon, where astronauts will explore it in...

asteroid defies gravity

Whitney Heins, University of Tennessee at Knoxville Researchers at the University of Tennessee at Knoxville (UT) have made a novel discovery that may potentially protect the world from future collisions with asteroids. The team studied near-Earth asteroid 1950 DA and discovered that the body, which rotates so quickly it defies gravity, is held together by cohesive forces, called van der Waals, never before detected on an asteroid. The findings, published in this week’s edition of...

Brett Smith for redOrbit.com - Your Universe Online Proposed studies for NASA’s missions to capture and redirect an asteroid are set to kick off in July. The space agency said these studies should inform not only the future asteroid mission, but also future missions to Mars. "With these system concept studies, we are taking the next steps to develop capabilities needed to send humans deeper into space than ever before, and ultimately to Mars, while testing new techniques to protect...

Brett Smith for redOrbit.com - Your Universe Online Last year, a massive asteroid that had gone undetected exploded over Chelyabinsk, Russia in a huge fireball and another, much bigger asteroid spotted in April is expected to buzz past Earth this weekend. While the incoming HQ124 asteroid, aka “the Beast,” is not expected to make contact with the Earth’s atmosphere, professional skywatchers will be keeping close tabs on the massive space rock nonetheless. “What’s...

[ Watch the Video: Space Probes Could One Day Help Deflect Asteroids ] Lee Rannals for redOrbit.com - Your Universe Online Scientists are conducting experiments to figure out how space probes could be used to deflect potentially hazardous asteroids. Researchers at Fraunhofer Institute for High-Speed Dynamics have begun initial experiments to verify the possibility of deflecting asteroids by impacting them with heavy masses at high speeds. They said the principle behind their research...

Asteroid -- An asteroid, also called a minor planet or planetoid, is a member of a group of small, planet-like bodies that are part of our solar system. They are believed to be remnants of the interstellar clouds, nebula, that were not incorporated into planets during the formation of the solar system. The largest asteroid in the inner solar system is Ceres with a diameter of 1003 km. It also was the first to be discovered, by Giuseppe Piazzi on January 1, 1801. Nowadays, over 9000...

Asteroid Belt -- The Asteroid belt is a region of the solar system falling roughly between the planets Mars and Jupiter where the greatest concentration of asteroid orbits can be found. It is believed that, during the first million years of the solar system history, planets formed by accretion of planetesimals. Ripetute collisions led to the familiar rocky planets and to the gas giant's cores. However, in this zone of the system the strong gravity of Jupiter inhibited the final stages...

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...
