641 Agnes, provisional designation 1907 ZX, is a stony asteroid and slow rotator from the inner regions of the asteroid belt, about 9 kilometers in diameter. It was discovered on 8 September 1907, by German astronomer Max Wolf at Heidelberg Observatory in southern Germany.
The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 1.9–2.5 AU once every 3 years and 4 months (1,208 days). Its orbit is tilted by 2 degrees to the plane of the ecliptic and shows an eccentricity of 0.13. The asteroid has a notably long rotation period of 178 hours and an albedo in the range of 0.20 to 0.30, according to the surveys carried out by the Japanese Akari satellite and the U.S Wide-field Infrared Survey Explorer with its NEOWISE mission, as well as further ground-based observations.
