As of September 2014, it has been observed 26 times with a data-arc span of 349 days. It is an Apollo asteroid and its semi-major axis (1.0016 AU) is very similar to that of the Earth. It has relatively high orbital eccentricity (0.4521) and high orbital inclination (49.9761°). With an absolute magnitude of 21.7, it has a diameter in the range 130–300 m (for an assumed albedo range of 0.04–0.20). Quasi-satellite dynamical state and orbital evolution 2013 LX 28 has been identified as an Earth quasi-satellite following a kidney-shaped retrograde orbit around the Earth.
