1280 Baillauda, provisional designation 1933 QB, is a dark background
Uccle Observatory in 1933, the asteroid was named after French astronomer Jules Baillaud.[9]
Discovery
Baillauda was discovered by Belgian astronomer
Eugène Delporte at the Royal Observatory of Belgium in Uccle on 18 August 1933.[9] On the following night, it was independently discovered by Soviet astronomer Grigory Neujmin at Simeiz Observatory on the Crimean peninsula.[2] The Minor Planet Center only recognizes the first discoverer.[9]
The asteroid was first identified as A912 GB at
Heidelberg Observatory in April 1912. The body's observation arc begins with its official discovery observation at Uccle in August 1933.[9]
Orbit and classification
Baillauda is a non-
semi-major axis of 3.41). Its orbit has an eccentricity of 0.05 and an inclination of 6° with respect to the ecliptic.[1]
Physical characteristics
In the
Tholen classification, Baillauda is an X-type asteroid.[1] The Lightcurve Data Base amends this Tholen spectral type and derives a primitive P-type based on the asteroid's low albedo (see below).[3]
Rotation period
In August 1990, a rotational
U=2).[7]
Diameter and albedo
According to the surveys carried out by the Infrared Astronomical Satellite
albedo of 0.0505 and 0.045, respectively.[5][6] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is an albedo of 0.0505 and a diameter of 50.83 kilometers based on an absolute magnitude of 10.33.[3]
Naming
This
513).[2] Jules was the son of prolific astronomer Benjamin Baillaud (1848–1934), after whom the lunar crater Baillaud
was named.
The official naming citation was mentioned in H 117).[2]
