Columbia (
minor planet designation: 327 Columbia) is a stony asteroid from the middle region of the asteroid belt, approximately 26 kilometers in diameter. It was discovered on 22 March 1892, by French astronomer Auguste Charlois at Nice Observatory in southeast France.[11] It is named after Christopher Columbus (1451–1506).[3]
Description
Columbia orbits the Sun at a distance of 2.6–2.9 AU once every 4 years and 8 months (1,691 days). Its orbit has an eccentricity of 0.06 and an inclination of 7° with respect to the ecliptic.[1] The body's observation arc begins the night after its official discovery at Nice.[11]
Physical characteristics
In the
SMASS taxonomy, Columbia has been characterized as a Sl-type, an intermediary between the common S-type and rather rare L-type asteroids.[1]
Rotation period and spin axis

U=3).[8]
In 2016, a modeled lightcurve was derived from various photometric database sources, giving a concurring period of 5.93183 hours and a spin axis of (52.0°, 43.0°) in ecliptic coordinates.[9]
Diameter and albedo
According to the surveys carried out by the Infrared Astronomical Satellite
albedo between 0.214 and 0.250.[5][6][7] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.2565 and a diameter of 26.24 kilometers using an absolute magnitude of 10.0.[4]
