In 1846, he predicted the existence and position of the planet Neptune by applying the mathematics of celestial mechanics.

[8] In March 2016, a modeled rotation period for Leverrier was published using data from the Lowell Photometric Database (LPD).

Using lightcurve inversion and convex shape models, as well as distributed computing power and the help of individual volunteers, a period of 8.015 hours could be obtained for this asteroid from the LPD's sparse-in-time photometry data (U=n.a.).

[5] According to the survey carried out by the Infrared Astronomical Satellite IRAS, Leverrier measures 6.8 kilometers in diameter and its surface has an albedo of 0.166.

[4] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.181 and a concurring diameter of 6.8 kilometers, with an absolute magnitude of 13.3.
