1665 Gaby, provisional designation 1930 DQ, is a stony asteroid and a slow rotator from the inner regions of the asteroid belt, about 11 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 27 February 1930.[8]
The S-type asteroid orbits the Sun at a distance of 1.9–2.9 AU once every 3 years and 9 months (1,370 days). Its orbit shows a rather high eccentricity of 0.21 and is tilted by 11 degrees to the plane of the ecliptic. It has a very slow rotation period of 66–68 hours.[6][7] and an albedo of 0.26 determined by the WISE/NEOWISE surveys.[4][5]
The asteroid was named by the discoverer after his daughter-in-law, Gaby Reinmuth.[2]
