Key Facts

Overview

2010 RF12 is a small asteroid orbiting the sun inside the belt of the inner planets. NASA JPL does not treat 2010 RF12 as potentially hazardous, because its orbit never carries it near Earth.

One lap around the sun takes 2010 RF12 399 days (1.09 years). Over that circuit it swings between 0.86 AU and 1.26 AU from the sun, travelling at an average of 28.93 km/s. At 0.0 kilometers across, 2010 RF12 is roughly the size of a school bus or smaller.

Close Approaches

The orbit of 2010 RF12 stays well clear of Earth's. Its predicted passes are listed below.

These 84 passes come from orbital simulations run by NASA JPL's CNEOS.
