It orbits the Sun in the inner main-belt at a distance of 1.8–2.7 AU once every 3 years and 5 months (1,252 days). Its orbit has an eccentricity of 0.20 and an inclination of 29° with respect to the ecliptic.^[1] No precoveries were taken. The asteroid's observation arc begins 20 days after its discovery.^[9]

Schwaar has been characterized as a S-type asteroid by Pan-STARRS photometric survey.^[8]

This minor planet was named in memory amateur astronomer Pierre–Yves Schwaar (1946–2000), member of the Saguaro Astronomy Club (SAC), telescope maker, and photographer of the night sky.^[2] The official naming citation was published by the Minor Planet Center on 9 January 2001 (M.P.C. 41939).^[10] The native Swiss amateur astronomer and immigrant to the U.S. was also an inventor and master craftsman, a model rocketeer, an USAF aircraft mechanic, a Vietnam veteran, and an eclipse chaser.
