1660 Wood, provisional designation 1953 GA, is a stony Phocaea asteroid from the inner regions of the asteroid belt, approximately 12 kilometers in diameter. It was named after British–South African astronomer Harry Edwin Wood.
Wood was discovered on 7 April 1953, by South African astronomer Jacobus Bruwer at Johannesburg Observatory in South Africa. It was the second numbered discovery made by Bruwer. He also discovered the minor planets 1658 Innes, 1794 Finsen, and 3284 Niebuhr. The asteroid 1811 Bruwer was named in his honour by the Dutch, Dutch-American astronomer trio of the Palomar–Leiden survey.
Wood is a S-type asteroid asteroid and member of the Phocaea family. It orbits the Sun at a distance of 1.7–3.1 AU once every 3 years and 9 months (1,354 days). Its orbit has an eccentricity of 0.30 and an inclination of 21° with respect to the ecliptic. It was first identified as 1931 KL at Lowell Observatory in 1931, extending the body's observation arc by 22 years prior to its official discovery observation.
From January to March 2012, four rotational lightcurves of Wood were obtained from photometric observations taken by astronomers Julian Oey, Kevin Hills, and Xianming Han. Lightcurve analysis gave a concurring rotation period of 6.809 hours with a brightness variation between of 0.14 and 0.26 magnitude (U=3/3/3/2+).
