247 Eukrate is a rather large main-belt asteroid. It is dark and probably a primitive carbonaceous body. The asteroid was discovered by Robert Luther on March 14, 1885, in Düsseldorf. It was named after Eukrate, a Nereid in Greek mythology.
In 2001, the asteroid was detected by radar from the Arecibo Observatory at a distance of 1.18 AU. The resulting data yielded an effective diameter of 134 ± 15 km.[2]
