It was named after the astronomer Johann Heinrich Lambert. This was the second of Coggia's five asteroid discoveries. This object is orbiting the Sun at a distance of 2.73 AU with a moderate eccentricity of 0.24 and an orbital period of 4.50 years. The orbital plane is inclined at an angle of 10.6° to the plane of the ecliptic. It is spinning with a rotation period of 10.67 hours. The spectrum matches a classification of a C-type asteroid, which may mean it has a composition of primitive carbonaceous materials. It is a dark object as indicated by the low albedo and has an estimated size of about 131 km. Notes References B.
