1665 Gaby, provisional designation 1930 DQ, is a stony

Heidelberg Observatory in southern Germany.[12] It was later named after Gaby Reinmuth, the discoverer's daughter-in-law.[2]

Orbit and classification

Gaby orbits the Sun at a distance of 1.9–2.9 

precoveries were taken, and no prior identifications were made of Gaby. The body's observation arc begins 2 months after its official discovery observation at Heidelberg.[12]

Physical characteristics

In the

Tholen classification, Gaby is a common S-type asteroid.[1]

Lightcurves

U=2).[7]

This is a longer-than average rotation, since most minor planets have a period between 2 and 20 hours (see

U=n.a.).[8][9]

Diameter and albedo

According to the survey carried out by NASA's

albedo between 0.253 and 0.278.[4][5][6] The Collaborative Asteroid Lightcurve Link adopts Petr Pravec's revised WISE data with an albedo of 0.2532 and a diameter of 11.01 kilometers using an absolute magnitude of 11.9±0.2.[3][6]
