[4] 2014 OL339 was discovered on 29 July 2014 by Farid Char of the Chilean University of Antofagasta.
The intended target of the program was the Apollo asteroid 2013 VQ4 but F. Char identified 2014 OL339 as a streak near the edge of the observed field.
It moves in a kidney-shaped path going from east to west relative to Earth ("retrograde", the opposite way from the Moon).
Before and after this episode it passes in and out of other types of co-orbital orbits, such as being a trojan or a "passing object" (one whose relative longitude to Earth can attain any value, which is not the case for a quasi-satellite or a Trojan).
[4] With an absolute magnitude of 22.9,[1] it has an estimated diameter of approximately 170 meters for an albedo of 0.25, which is typical for stony asteroids.
