SALT LAKE CITY - Although scientists are unable to really define what it is, they just know that a large mass travelling through space narrowly missed earth Tuesday night. The object passed within about 80,000 miles from earth -- the equivalent of one third the distance from the Earth to the moon. Very close concerning the vastness of space.

The object -- about the size of a bus -- could have potentially created devastating consequences for life on our home planet if it collided.

The object, named 2010 A-L 30, could only be seen with the aid of a high power telescope.

There's a little bit of a debate concerning its origin. Scientists think that it may be just space rock and hypothesize that it may be part of a small minor planet. Another idea is that it's a piece of returning space junk that was originally sent to Venus and has swung around through gravitational forces. Experts lean toward the premise that it originated from a small minor planet.
