It was discovered on 18 December 1995, by astronomers of the Spacewatch program at Kitt Peak National Observatory in Arizona, United States.
[4] Leifandersson is a non-family asteroid of the main belt's background population when applying the Hierarchical Clustering Method to its proper orbital elements.
[4] In February 2011, a rotational lightcurve of Leifandersson was obtained from photometric observations by astronomers at the Palomar Transient Factory in California.
Lightcurve analysis gave a rotation period of 3.758 hours with a brightness amplitude of 0.33 magnitude (U=2).
[4] This minor planet was named after Swedish astronomer Leif Erland Andersson (1943–1979), who calculated the first observable transits of Pluto and Charon and also co-produced a catalogue of lunar craters.
