Latest Asteroids Stories
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.
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.
Researchers at the University of Tennessee at Knoxville have made a novel discovery that may potentially protect the world from future collisions with asteroids.
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.
On Thursday, June 19, NASA will host a televised update on recent progress and upcoming milestones in the agency's efforts to identify, capture and relocate an asteroid, and send astronauts to take samples of it in the 2020s.
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.
WASHINGTON, March 21, 2014 /PRNewswire-USNewswire/ -- In support of NASA's Asteroid Redirect Mission - a key part of the agency's stepping stone path to send humans to Mars - agency officials
As the next step in advancing NASA’s asteroid initiative, the agency will host an Opportunities Forum March 26 at NASA Headquarters in Washington.
Researchers 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 is similar to how the balls in a game of billiards get banged around from one side of the table to another.
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 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...
