Your House Will Not Be Destroyed by an Asteroid, but You Can Calculate the Odds If You Want

Did you know that every year, about one asteroid between 16 and 33 feet wide hits the Earth? And when you look at asteroids that are less that 16 feet wide, the total that hit the Earth jumps to around 500? Crap, that means that you have a pretty solid chance of your house being destroyed by an asteroid, right? …

Asteroid Flyby to be Live-Streamed by NASA

On February 15, tomorrow, an asteroid named 2012 DA14 will fly within several thousand miles of the surface of the Earth. At its closest approach the asteroid will come within 17,200 miles of the Earth’s surface – a harrowingly close miss that comes well within the ring of man-made geosynchronous satellites that orbit the Earth. The flyby will set a …

Asteroid Worth $195B to Swing By Earth on February 15

On February 15 an asteroid named 2012 DA14 will pass very close to the Earth. It will swing within just 17,200 miles of the planet’s surface, which is well within the orbit of the man-made geosynchronous satellites that orbit the Earth. By coming within just one-thirteenth the distance from the Earth to the moon, the asteroid will set a record …

Earth-Threatening Asteroid to be Visited by NASA’s OSIRIS-REx

One week from today an asteroid will swing within just 17,200 miles of Earth – closer than geosynchronous satellites that orbit the planet. While there is no chance of an impact event on February 15, there are other asteroids that could collide with the Earth sometime in the future. To prepare for (and hopefully prevent) such a disaster, NASA has …

Asteroid Named “Wikipedia” Officially Documented

Considering just how many asteroids there are in the asteroid belt, it can be difficult to come up with acceptable names for all of them. So, they are given obscure provisional names until a naming organization can bestow names on select celestial bodies. Most named asteroids are named after astronomers themselves, or the relatives of astronomers. This week, Wikimedia announced …

Asteroid to Give Earth a Near Miss on February 15

NASA this weekend revealed that an asteroid named 2012 DA14 will come very close to Earth on February 15. The object will swing within 27,700 kilometers (17,200 miles) of the Earth’s surface – close enough to pass within the geosynchronous satellites that orbit the planet, and only around one-thirteenth the distance from the Earth to the moon. NASA researchers stated …

Doomsday Asteroid Deflection Mission Tests Concepts

The European Space Agency (ESA) today announced that it is appealing for research ideas that could help develop a future mission to deflect life-threatening asteroids. It is asking for both ground and space-based ideas to improve scientist’s understanding of high-speed collisions between man-made and natural objects. No asteroids are currently on a collision course with Earth (though some are coming …

“Doomsday” Asteroid Won’t Hit Earth in 2036

Earlier this week, astronomers with the European Space Agency (ESA) announced that they were collecting data on the asteroid Apophis as it made its most recent approach to Earth. The data was, among other things, meant to narrow the prediction as to whether the asteroid might impact the Earth in 2036. Now, NASA has announced that Apophis will not be …

Vega Asteroid Belt Suggests Multiple Planets

Astronomers this week announced that they have discovered what could be an asteroid belt around the star Vega. NASA‘s Spitzer space telescope and the European Space Agency’s (ESA) Herschel Space Observatory were used to observe the star, which is the second brightest in the northern sky. Vega was found to have an astroid belt-like band of debris in both a …

Asteroid Apophis Approaches Earth, 2036 Impact Probability Still Uncertain

Over the past weekend, astronomers used the European Space Agency’s (ESA) Herschel Space Observatory to image an asteroid that will be giving the Earth a near-miss in 2029. The asteroid, named Apophis, was thought to have a 2.7% chance of striking the Earth in 2029 when it was discovered in 2004. New observations have ruled out an impact, but the …

Giant Asteroid “Speckles” Analyzed by NASA’s Dawn

New images released by NASA have provided scientists their best view yet of the black spots seen on the surface of the giant asteroid Vesta. The new research suggests that the protoplanet may have received the carbon-rich material through large impacts with other objects. The new study, published in the journal Icarus, is the most complete analysis of the material …

NASA Video Shows Three-Mile-Long Asteroid Swing By Earth

On Wednesday, December 12, the three-mile-long asteroid named “Toutatis” made its closest approach to earth. NASA scientists working at the Deep Space Network antenna in Goldstone, California were able to capture radar images of the object as it swung by. The images have been assembled into a video showing the asteroid as it tumbled past Earth. Toutatis was only 6.9 …
