Overview

494710 (2005 MO13) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2005 MO13 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2005 MO13 orbits the sun every 293 days (0.80 years), coming as close as 0.51 AU and reaching as far as 1.22 AU from the sun. Based on its brightness and the way it reflects light, 2005 MO13 is probably between 0.186 to 0.415 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2005 MO13's orbit is 0.04 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

2005 MO13 has 31 close approaches predicted in the coming decades:
