Its name was chosen by Martin Hoek, the director of the Utrecht Observatory, in reference to Mnemosyne, a Titaness in Greek mythology.

[5] This asteroid is orbiting in the outer main belt at a distance of 3.149 AU from the Sun with an eccentricity (ovalness) of 0.118 and a period of 5.58811 a.

The orbital period of this asteroid is close to a 2:1 commensurability with Jupiter, which made it useful for perturbation measurements to derive the mass of the planet.

[6][7] Photometry measurements made at the Oakley Observatory during 2006 produced a lightcurve with a rotation period of 12.06±0.03 h and an amplitude of 0.14±0.01 in magnitude.

[8] Subsequent observations at Organ Mesa Observatory in 2019 showed this period was not a good fit to a longer light curve.
