Latest Asteroids Stories
Within NASA’s new FY2014 budget proposal lies a project known as the Asteroid Retrieval and Utilization Mission. This project would be the first to capture a small near-Earth asteroid and safely redirect it to a lunar orbit so that astronauts can visit and explore it. Such a mission would expand scientific knowledge of the origins of both humanity and the universe.
The giant Chicxulub crater in Yucatan is evidence that sometime around 65 million years ago a massive asteroid smashed into the earth wiping out most life that existed at that time, including all non-avian dinosaurs. While it is hard to imagine a similar scenario taking place today, there is currently little that we could do but sit and “pray.”
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.
In the wake of the recent meteor explosion above Russia, the European Space Agency has announced the selection of a target for their proposed Asteroid Impact and Deflection Assessment (AIDA).
A pair of California scientists unveiled a proposal this week for a system that could eliminate threatening asteroids or meteors, just as a meteorite explodes over Russia and an asteroid grazes past Earth within a 24-hour span.
Researchers have used three-dimensional computer simulations to reconstruct how an asteroid called Vesta collided with other asteroids twice over a billion years ago to explore the origins of our Solar System.
Planetary Resources, a company aimed at mining asteroids, says that its Arkyd-100 Series of spacecraft will be assisting in the detection and characterization of potentially hazardous asteroids near Earth.
Deep Space Industries announced this week that DA14, the asteroid making a close approach to Earth this week, could be worth up to $195 billion, assuming it were in a different orbit.
A record-setting asteroid about the size of half a football field will be making a close flyby to Earth just after Valentine's Day.
Deep Space Industries announced on Tuesday that it plans to send a fleet of asteroid-prospecting spacecraft out into the solar system.
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...
