Asteroid
1576 Fabiola , provisional designation 1948 SA , is a Themistian
asteroid from the outer regions of the
asteroid belt , approximately 27 kilometers in diameter. It was discovered on 30 September 1948, by Belgian astronomer
Sylvain Arend at the
Royal Observatory of Belgium in Uccle.
[15] The asteroid was named after
Queen Fabiola of Belgium .
[2]
Orbit and classification
Fabiola is a Themistian asteroid that belongs to the
Themis family (
602 ), a very large
family of carbonaceous asteroids, named after
24 Themis .
[3]
[4]
[16] It orbits the Sun in the
outer main-belt at a distance of 2.6–3.7
AU once every 5 years and 7 months (2,042 days). Its orbit has an
eccentricity of 0.17 and an
inclination of 1
° with respect to the
ecliptic .
[1]
The asteroid was first identified as 1931 RV at
Simeiz Observatory in September 1931. The body's
observation arc begins with its identification as 1931 TQ2 at
Lowell Observatory in October 1931, almost 17 years prior to its official discovery observation at Uccle.
[15]
Physical characteristics
In the
Tholen classification , Fabiola has an ambiguous
spectral type , similar to the
B-type asteroids ("bright" carbonaceous asteroids), yet with an "unusual" spectra (BU).
[1]
Rotation period
In November 1976, a rotational
lightcurve of Fabiola was obtained from photometric observations by Swedish astronomer
Claes-Ingvar Lagerkvist at
Uppsala Observatory . Lightcurve analysis gave a
rotation period of 6.7 hours with a brightness amplitude of 0.2
magnitude (
U=2 ).
[13]
Diameter and albedo
According to the surveys carried out by the Infrared Astronomical Satellite
IRAS , the Japanese
Akari satellite and the
NEOWISE mission of NASA's
Wide-field Infrared Survey Explorer , Fabiola measures between 21.33 and 30.150 kilometers in diameter and its surface has an
albedo between 0.0746 and 0.123.
[5]
[6]
[7]
[8]
[9]
[10]
[11]
[12]
The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0913 and a diameter of 27.25 kilometers based on an
absolute magnitude of 11.04.

[8]
Naming
This
minor planet was named after
Queen Fabiola of Belgium (1928–2014).
[2] The official
naming citation was published by the
Minor Planet Center on 31 January 1962 (
M.P.C. 2116 ).
