It was discovered on 12 January 1983, by American astronomer Brian Skiff at Lowell's Anderson Mesa Station in Flagstaff, Arizona.[19] The asteroid was named after amateur astronomer Pierre–Yves Schwaar.[2] Orbit and classificationSchwaar is a member of the Phocaea family ({{small|701}}),[4] a rather small group of asteroids with similar orbital characteristics, named after its largest member, 25 Phocaea. 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. No precoveries were taken. The asteroid's observation arc begins 20 days after its discovery.[19]Physical characteristicsSchwaar has been characterized as a S-type asteroid by Pan-STARRS photometric survey.[14]LightcurvesA rotational lightcurve of Schwaar was obtained from photometric observations made at the Hunters Hill Observatory ({{small|E14}}), Australia, and collaborating stations in December 2006. The lightcurve gave a rotation period of {{val|6.8}} hours with a brightness variation of 0.17 in magnitude ({{small|U=3-}}).[9] Diameter and albedoAccording to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, Schwaar measures 5.3 and 5.9 kilometers in diameter and its surface has an albedo of 0.182 and 0.185, respectively,[8][7] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for members of the Phocaea family of 0.23, and calculates a diameter of 5.0 kilometers with an absolute magnitude of 13.7.[3] NamingThis 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 ({{small|M.P.C. 41939}}).[30] 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.
