Orbit and classification
Kordula is a non-
Heidelberg Observatory on 11 October 1920, the night after its official discovery observation.[1]
Naming
This
Saint Cordula
.
Reinmuth's calendar names
As with 22 other asteroids – starting with
Lutz Schmadel, the author of the Dictionary of Minor Planet Names learned about Reinmuth's source of inspiration from private communications with Dutch astronomer Ingrid van Houten-Groeneveld, who worked as a young astronomer at Heidelberg.[2]
Physical characteristics
In the
Tholen classification, Kordula is closest to an F-type asteroid, and somewhat similar to that to a common carbonaceous C-type asteroid.[3][11]
Rotation period
In October 1999, a rotational
Diameter and albedo
According to the surveys carried out by the
Further published mean-diameters and albedos by the WISE team include (77.941±26.705 km), (87.10±25.52 km), (87.29±33.02 km), and (93.192±1.325 km) with corresponding albedos of (0.044±0.024), (0.04±0.03), (0.04±0.03), and (0.0308±0.0066).[11][7] The Collaborative Asteroid Lightcurve Link adopts the results from IRAS, that is, an albedo of 0.0352 and a diameter of 87.21 km based on an absolute magnitude of 9.55.[7][11]
