Initial reports put last Friday’s (Feb 15) Chebarkul meteorite that exploded over Russia’s Urals region at about 10 tons. But after careful analysis, NASA released new information that puts the meteorite closer to 10,000 tons—1,000 times larger than the estimates size reported by the Russian Academy of Sciences.
The first firm details of the 15 February asteroid impact in Russia, the largest in more than a century, are becoming clear.
On February 15, asteroid 2012 DA14 passed extraordinarily close to the earth.
Just one day after a spectacular meteor exploded over Russian skies, shattering windows and injuring more than a 1,200 people, Cubans were treated to a similar event, albeit on a much smaller scale.
As reports continue to stream in through various media outlets on injuries, damages, and the science behind such events, it seems this morning’s (February 15) meteor strike in Russia’s Ural Mountains region has left a pretty big impression far and wide.
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.
A meteor streaked across Russia’s early morning skies on Friday before violently exploding, sending a rain of debris onto the Earth below. The flash and boom shattered windows and meteor particles left damage in its wake, injuring more than 900 people in the Ural Mountains region.
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.
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...
