5171 Augustesen, provisional designation 1987 SQ3, is a background
rotation period of 480 hours and possibly an elongated shape.[3] It was named after Danish astronomer Karl Augustesen.[1]
Orbit and classification
Augustesen is a non-
It orbits the Sun in the
Heidelberg and Goethe Link Observatory, where the body's observation arc begins in September 1953, or 34 years prior to its official discovery observation at Brorfelde.[1]
Physical characteristics
Augustesen has been characterized as an X-type asteroid by Pan-STARRS' photometric survey.[11] It is also an assumed S-type asteroid.[3]
Rotation period
In October 2006, a rotational
U=3).[10][a] The asteroid is a slow rotator with a period much longer than the typical 2 to 20 hours measured for most observed asteroids. Augustesen is also a suspected tumbler with a non-principal axis rotation, also known as "tumbling".[3]
An alternative measurement by
U=1).[9]
Diameter and albedo
According to the surveys carried out by the Japanese
The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 6.81 kilometers based on an absolute magnitude of 13.2.[3]
Naming
This
discoverer of minor planets. For several decades he had been an observer using the Schmidt telescope at the discovering Brorfelde Observatory in Denmark, after which the asteroid 3309 Brorfelde was named.[1]
The corrected official naming citation was published by the
JPL SBDB still shows the (incorrect) discovery date of that other asteroid.[12]
