It was discovered by American female astronomer Eleanor Helin at the U.S. Palomar Observatory, California, on 22 January 1990.The S-type asteroid orbits the Sun at a distance of 1.7–3.0 AU once every 3 years and 7 months (1,304 days). Its orbit shows a notable eccentricity of 0.29 and an inclination of 22 degrees from the plane of the ecliptic. The Collaborative Asteroid Lightcurve Link (CALL) also classifies it as a Mars-crossing asteroid, because its perihelion lies between 1.3 and 1.668 AU (with no rounding). On the other hand, the JPL Small-Body Database exclusively classifies the body as a main-belt and not as a Mars-crosser, since its perihelion of 1.6685 AU is larger than the aphelion of Mars (1.666 AU). Hence the body does not even classify for an outer Mars grazer. A photometric light-curve analysis by Czech astronomer Petr Pravec at Ondřejov Observatory in 2010, rendered a well-defined rotation period of 7000331620000000000♠3.3162±0.0003 hours with a brightness amplitude of 0.28 in magnitude. According to the surveys carried out by NASA's Wide-field Infrared Survey Explorer and its subsequent NEOWISE mission, the asteroid has a high albedo of 0.35 and 0.31 with a corresponding diameter of 5.0 and 5.7 kilometers, respectively,while CALL assumes an albedo of 0.20, which is a more typical value for stony asteroids, and calculates a diameter of 4.7 kilometers.The minor planet was named after a cousin of the discoverer, Barbara Hendricks Doore (b. 1933). She has been described as an active sports enthusiast with boundless energy, who excelled at sailing and golf. As a popular leader/volunteer, she has devoted much of her later years to the Boys and Girls Club of Cathedral City, California."@en }
