Talk about too close for comfort. In a rare cosmic encounter, an asteroid will buzz Earth next week, missing our planet by a mere 17,200 miles (27,700 kilometers).
Designated 2012 DA14, the space rock is approximately 150 feet (45 meters) across, and astronomers are certain it will zip harmlessly past our planet on February 15—but not before making history. It will pass within the orbits of many communications satellites, making it the closest flyby on record. (Read about one of the largest asteroids to fly by Earth.)
“This is indeed a remarkably close approach for an asteroid this size,” said Paul Chodas, a research scientist at NASA’s Jet Propulsion Laboratory Near Earth Object (NEO) program office in Pasadena, California.
“We estimate that an asteroid of this size passes this close to the Earth only once every few decades.”
The giant rock—half a football field wide—was first spotted by observers at the La Sagra Observatory in southern Spain a year ago, soon after it had just finished making a much more distant pass of the Earth at 2.6 million miles (4.3 million kilometers) away.
This time around however, on February 15 at 2:24 p.m. EST, the asteroid will be passing uncomfortably close—ten times closer than the orbit of the moon—flying over the eastern Indian Ocean near Sumatra (map). (Watch: “Moon 101.”)
