Asteroid to pass close to Earth on Feb 15; no impact seen
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 on Thursday.

The celestial visitor, known as 2012 DA14, was discovered in 2012 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 February 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 pm 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).

"Although they wouldn't (cause) a global catastrophe if they impact the Earth, they still do a lot of regional destruction," said Lindley Johnson, who oversees the Near-Earth Object Observations Program at NASA headquarters in Washington DC.

NASA has been on a mission to find and track all near-Earth objects that are .62 miles (1 km) in diameter or larger. The effort is intended to give scientists and engineers as much time as possible to learn if an asteroid or comet is on a collision course with Earth, in hopes sending up a spacecraft or taking other measures to avert catastrophe.

About 66 million years ago, a 6-mile diametre (10 km) object smashed into what is now the Yucatan Peninsula in Mexico leading to the demise of the dinosaurs as well as most plant and animal life on Earth.

The planet is regularly pelted with objects from space, adding up to about 100 tons of material per day, Yeomans said.

"Basketball-sized objects come in daily. Volkswagen-sized objects come in every couple of weeks. As you get to larger and larger sizes the number of objects out there is less and less, so the frequency of hits goes down," Yeomans said.

Something the size of DA14 can be expected to strike Earth about every 1,200 years.

"For objects of this size, this is the closest predicted encounter that we're aware of," Yeomans said.
