Another asteroid to give Earth a close shave June 27, 2011

(PhysOrg.com) -- A newly discovered house-sized asteroid will miss the Earth by less than 17,700 km (11,000 miles) on Monday June 27, 2011. That’s about 23 times closer than the Moon. The size and location of the asteroid, named 2011 MD, should allow observers in certain locations to take a look at the space rock, even with small telescopes. It’s closest approach will be at 13:26 UTC on June 27.

According to Skymania, 2011 MD was found just yesterday, June 22, by LINEAR, a pair of robotic telescopes in New Mexico that scan the skies for Near Asteroids.

As of now, asteroid 2011 MD is estimated to be between 9 to 45 meters (10 to 50 yards) wide. Dr. Emily Baldwin, of Astronomy Now magazine, said there is no danger of the asteroid hitting Earth, and even if it did enter the atmosphere, an this size would “mostly burn up in a brilliant fireball, possibly scattering a few meteorites.”

To find out updated information on 2011 MD’s ephemeris, physical parameters and more, including an orbit diagram and close-approach data, see this page on JPL’s Solar System Dynamics website.

That's not really news, a house sized meteor is small. These hit the earth everyday, what do you think shooting stars are? I guess it's news that they can detect them and happened to have been looking in the right place at the right time. I guess its a great tool for meteorite hunters.

Umm... gunslingor1: A meteor 150 feet wide would hit with the same force as a 20 megaton nuclear explosion, and would create a hole in the Earth almost one mile in diameter. Read up on Meteor Crater in Arizona. Meteors of this size absolutely do NOT hit the Earth every day. Do you know what causes "shooting stars"? Rocks roughly the size of a pencil eraser -- travelling about 20 times faster than a bullet.

We should be more concerned about gunslingor.

That may be true for house-sized meteorites that hit the ground going that fast. A house-sized meteor, however, would expend its energy high up in the atmosphere where it would most likely break up catastrophically in a large fireball that would be amazing to see, but would be mostly harmless. Surviving fragments from the fireball might hit the ground, but they'd be slowed by atmospheric friction to the point where they would do little if any damage when they land.

Close shave, huh?

They should call this asteroid Gillette.

facts

30 meter crater, 2 meter bolide.

see page 25

4 meter wide bolides strike the Earth ~every 15 years.

6 meter wide bolides strike ~every 35 years.
