674 Rachele is a minor planet orbiting the Sun. It was discovered by Wilhelm Lorenz on October 28, 1908 in Heidelberg, and was named by orbit computer Emilio Bianchi after his wife.[1] This is classified as an S-type asteroid,[2] indicating a stony composition.
Measurements made using the adaptive optics system at the W. M. Keck Observatory give a size estimate of 89 km. It has a size ratio of 1.08 between the major and minor axes. By comparison, measurements reported in 1998 from the IRAS observatory give a similar size of 97 km and a ratio of 1.15.[3]
