2500 Alascattalo, provisional designation 1926 GC, is a stony Flora asteroid from the inner regions of the asteroid belt, approximately 8 kilometers in diameter.
The asteroid was discovered on 2 April 1926, by German astronomer
Heidelberg Observatory in southern Germany.[9] It was later named for the fictional moose–walrus Alascattalo creature.[2]
Orbit and classification
Alascattalo is a member of the
precoveries were obtained prior to its discovery.[9]
Physical characteristics
Alascattalo has been characterized as a common, stony S-type asteroid.[3]
Rotation period
A rotational
U=3-).[6]
A previous lightcurve with a concurring period of 2.754 hours and a similar amplitude of 0.15 was already obtained by French amateur astronomer
U=2).[7]
Diameter and albedo
According to the survey carried out by the
albedo of 0.21 and 0.27, respectively,[4][5] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – which derives from 8 Flora, the largest member and namesake of this orbital family – and calculates a diameter of 8.2 kilometers with an absolute magnitude of 12.6.[3]
Naming
This minor planet was named after the mythological creature "Alascattalo", a fictional chimera between a moose and a walrus.[2]
According to legend, it was genetically bred by miners during the
M.P.C. 19332).[10]
