Astronomers Monitor Asteroid To Pass Near Mars

Astronomers funded by NASA are monitoring the trajectory of an asteroid estimated to be 164 feet wide that is expected to cross Mars' orbital path early next year.

The asteroid was initially being monitored by The Near Earth Object Observation Program, commonly called "Spaceguard,” to determine if any could be potentially hazardous to our planet. It was determined that the asteroid will not be a threat to earth but it may however, potentially impact mars.

Because of current uncertainties about the asteroid's exact orbit, there is a 1-in-75 chance of the asteroid impacting Mars. “We estimate such impacts occur on Mars every thousand years or so” said Steve Chesley, a scientist at JPL. If the asteroid were to collide with mars, it is calculated that it would hit at 30,000 mph and could create a crater over half a mile wide.
