2513 Baetslé, provisional designation 1950 SH, is a stony Flora asteroid from the inner regions of the asteroid belt, approximately 16 kilometers in diameter.
It was discovered on 19 September 1950, by Belgian astronomer Sylvain Arend at the Royal Observatory in Uccle, Belgium.[8] It was later named after astronomer Paul-Louis Baetslé.[2]
Orbit and classification
Baetslé is a member of the
Heidelberg Observatory, extending the body's observation arc by 7 years prior to its official discovery observation.[8]
Physical characteristics
Baetslé takes 6.08 hours for a full a
rotation around its axis.[a] Two observations by the Infrared Astronomical Satellite, IRAS, showed an absolute magnitude of 13.40 and a low geometric albedo of 0.03.[3] While the size, rotational period and orbital data are commonly found among main-belt asteroids, the albedo was exceptionally low and suggested that the body's composition could be mostly carbonaceous
.
However, subsequent observations by the
NEOWISE mission gave a higher albedo of 0.22 and 0.30 and the Collaborative Asteroid Lightcurve Link derives a value of 0.33, assuming the body to be of a stony rather than of a carbonaceous composition.[3][5] This also concurs with the fact that Baetslé is a member of the Flora family of rather bright and stony asteroids.[3]
