NASA says a newly discovered asteroid that passed Earth in September is on its way around the solar system and may pass our planet again in 2032.
The asteroid was discovered in October of this year, about three weeks after it passed nearest to Earth on September 16, 2013
Even though the asteroid was 4.2 million miles away from our planet it is considered a 'near-Earth object'.
According to NASA's Near Earth Object Program Office "Near-Earth Objects or NEOs are comets and asteroids that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter Earth's neighborhood."
NEOs are important to track because there is a chance one could hit Earth, causing widespread destruction and major changes to climate.
The newly discovered asteroid was named '2013 TV135'
According to NASA's Near-Earth Object Program Office "the probability this asteroid could then impact Earth is only one in 63,000."
