Asteroid to make close pass by Earth on Feb. 15; no impact seen - Financial Express

Cape Canaveral, US: A small asteroid will pass closer to Earth next week than the TV satellites that ring the planet, but there is no chance of an impact, NASA said Thursday.

The celestial visitor, known as 2012 DA14, was discovered last year by a group of amateur astronomers in Spain. The asteroid is about the size of an Olympic swimming pool at 150 feet (46 m) in diameter and is projected to come as close as 17,100 miles (27,520 km) from Earth during its Feb. 15 approach.

That would make it the closest encounter since scientists began routinely monitoring asteroids about 15 years ago.

Television, weather and communications satellites fly about 500 miles (800 km) higher. The moon is 14 times farther away.

Even so, "no Earth impact is possible," astronomer Donald Yeomans, with NASA's Jet Propulsion Laboratory in Pasadena, Calif., told reporters during a conference call.

The time of the asteroid's closest approach will be 2:24 p.m. EST (1924 GMT), daylight in the United States, but dark in Eastern Europe, Asia and Australia where professional and amateur astronomers will be standing by with telescopes and binoculars to catch a view.

DA14 will soar through the sky at about 8 miles (13 km) per second. At that speed, an object of similar size on a collision course with Earth would strike with the force of about 2.4 million tons of dynamite. The last time that happened was in 1908 when an asteroid or comet exploded over Siberia, leveling 80 million trees over 830 square miles (2,150 sq km).
