Near Earth Object Update: Another Asteroid '2013 ET' To Pass Earth Saturday

Another Asteroid '2013 ET' To Pass Earth Saturday; When And Where To Watch It Live

 

NEAR EARTH OBJECT UPDATE:

8.3.2013


Well Folks,

We have another decent sized rock coming our way on Saturday.

The Asteroid dubbed NEO (near-Earth object) 2013 ET was discovered on March 3, 2013, by the Catalina Sky Survey.

The Asteroid is estimated to be approximately 64-140 meters (210-460 feet) wide and will pass 2.5 times the Moon's distance from our planet. At its maximum brightness on March 9th, NEO 2013 ET will be at a relatively dim magnitude of 17 -- not bright enough to view through a backyard telescope, but should be reasonably bright through Slooh telescopes in the Canary Islands, off the coast of west Africa. 

At a distance of 600,000 miles (960,000 kilometers) this Fly-By is 2.5LD (2.5X the distance of moon from Earth). The distance to moon’s orbit from the Earth differs between 363,104 to 406,696 kilometers (225,622 and 252,088 miles). 


Near Earth Asteroids:

Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.
On March 8, 2013 there were 1382 potentially hazardous asteroids.

A newly discovered asteroid with a size of a football field will zoom past Earth Mar. 9 just days after another cosmic rock cruised past Earth at a distance less than moon’s orbit.

City-block sized asteroid to make close flyby of Earth on Saturday

Harsh Gupta, ANI : Washington, Fri Mar 08 2013, 18:19 hrs


Asteroid
 An asteroid the size of a city block, will make its closest approach to Earth on Saturday, March 9th, less than 7 days after it was discovered, it has been revealed.
The asteroid dubbed NEO (near-Earth object) 2013 ET was discovered on March 3, 2013, by the Catalina Sky Survey.
The asteroid is estimated to be approximately 64-140 meters (210-460 feet) wide and will pass 2.5 times the Moon's distance from our planet. At its maximum brightness on March 9th, NEO 2013 ET will be at a relatively dim magnitude of 17 -- not bright enough to view through a backyard telescope, but should be reasonably bright through Slooh telescopes in the Canary Islands, off the coast of west Africa.

The asteroid will be travelling across the sky with a relative velocity of 11.88 kilometers per second or 26,552 mph, which is about 15 times faster than a rifle bullet. If asteroid 2013 ET were to hit Earth, the damage would be significant -- potentially destroying a small city.

Slooh Space Camera will cover its closest approach on Saturday, live on Slooh.com, free to the public, starting at 12:15 p.m. PST / 3:15 p.m. EST / 20:15 UTC -- accompanied by real-time discussions with Slooh president Patrick Paolucci, Slooh engineer Paul Cox, and documentary filmmaker Duncan Copp.
Viewers can watch live on their PC/MAC or iOS/Android mobile device.

"We only have a short viewing window of an hour or so from our Canary Islands observatory on March 9th, but we wanted to give the general public a front row seat to witness this new asteroid in real time as it passes by Earth," said Slooh president Patrick Paolucci.
