Asteroid will pass by Earth on Wednesday: NASA

New Delhi: An asteroid will safely pass Earth on Wednesday - closer than the distance from Earth to the moon. It happens about 20 times a year.

This asteroid, 2014 DX110, is estimated to be about 100 feet (30 meters) across. Its closest approach to Earth will be at about 2,17,000 miles (about 350,000 kilometers) from Earth at about 1 pm PST (4 pm EST) on March 5.

The average distance between Earth and its moon is about 239,000 miles (385,000 kilometers).

NASA detects, tracks and characterises asteroids and comets using both ground- and space-based telescopes.

The Near-Earth Object Observations Program, commonly called "Spaceguard," discovers these objects, characterises a subset of them and identifies their close approaches to determine if any could be potentially hazardous to our planet.
