Key Facts

Overview

246138 (2007 OG3) is a small asteroid circling the sun between Mars and Jupiter, inside the main asteroid belt. NASA JPL does not treat 246138 (2007 OG3) as potentially hazardous, because its orbit never carries it near Earth.

One lap around the sun takes 246138 (2007 OG3) 1,160 days (3.18 years). Over that circuit it swings between 1.12 AU and 3.21 AU from the sun, travelling at an average of 20.3 km/s. At 0.6 kilometers across, 246138 (2007 OG3) is roughly the size of the Golden Gate Bridge.
