Key Facts

Overview

186822 (2004 FE31) is a small asteroid orbiting the sun inside the belt of the inner planets. NASA JPL does not treat 186822 (2004 FE31) as potentially hazardous, because its orbit never carries it near Earth.

One lap around the sun takes 186822 (2004 FE31) 721 days (1.97 years). Over that circuit it swings between 0.86 AU and 2.29 AU from the sun, travelling at an average of 23.75 km/s. At 0.9 kilometers across, 186822 (2004 FE31) is roughly the size of the Golden Gate Bridge.
