1040 Klumpkea, provisional designation 1925 BD, is a Tirela

rotation period of 59.2 hours.[11] It was named after American astronomer Dorothea Klumpke.[2]

Orbit and classification

Klumpkea is the largest member of the

subclusters.[12]: 18, 23  The family is named after 1400 Tirela. Alternatively it is also known as the Klumpkea family by Milani and Knežević.[13][14]

It orbits the Sun in the

semi-major axis of 3.11 AU). Its orbit has an eccentricity of 0.19 and an inclination of 17° with respect to the ecliptic.[3] The body's observation arc begins at Algiers on its official discovery observation in January 1925.[1]

Naming

This

H99). The asteroid 339 Dorothea has also been named in her honor by its discoverer Max Wolf.[2]

Physical characteristics

Klumpkea's

albedo measured by SIMPS (see below).[11]

Rotation period and pole

In February 2002, a rotational

U=2), indicative of an elongated shape.[10]

In 2016, a modeled lightcurve gave a concurring sidereal period of 56.588±0.003 hours using data from the Uppsala Asteroid Photometric Catalogue, the

NOFS, the Catalina Sky Survey, and the La Palma surveys (950). The study also determined a spin axis for Klumpkea of (172.0°, 48.0°) in ecliptic coordinates (λ, β).[15]

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite

albedo between 0.063 and 0.245.[5][6][7][8][9] CALL assumes a carbonaceous standard albedo of 0.057 and calculates a diameter of 44.22 kilometers based on an absolute magnitude of 10.5.[11]
