1103 Sequoia (Bergedorf Observatory in Hamburg, Germany, who named it after the Sequoia National Park located in California.[19]
Orbit and classification
Sequoia is a bright member of the
semi-major axis of 1.93 AU). Its orbit has an eccentricity of 0.09 and an inclination of 18° with respect to the ecliptic.[1]
The body's
Algiers Observatory in December 1928, about 7 weeks after its official discovery observation at Bergedorf.[19]
Physical characteristics
In the
SMASS classification, it is a Xk-subtype that transitions between the X- and K-type asteroids.[1][4]
Rotation period
A large number of rotational
Poles
Sequoia's lightcurve has also been modeled several times and gave a concurring sidereal period of 3.03797, 3.037976 and 3.037977 hours.[12][13][a] In 2016, the large collaboration of astronomers also published a spin axis of (60.0°, −59.0°) in ecliptic coordinates (λ, β).[12]
Diameter and albedo
According to the surveys carried out by the Japanese
The Collaborative Asteroid Lightcurve Link adopts Petr Pravec's revised WISE results, that is, an albedo of 0.2813 and a diameter of 7.82 kilometers based on an absolute magnitude of 12.53.[4][9]
