Chaldaea ( minor planet designation: 313 Chaldaea) is a large Main belt asteroid. It is classified as a C-type asteroid and is probably composed of carbonaceous material. [2] It was discovered by Johann Palisa on 30 August 1891 in Vienna. It was named in honor of the Chaldeans, considered the founders of astrology. [3]
In 2003, the asteroid was detected by radar from the Arecibo Observatory at a distance of 1.07 AU. The resulting data yielded an effective diameter of 96 ± 14 km. [4]
