336 Lacadiera is a large Main belt asteroid. It is classified as a D-type asteroid and is probably composed of organic rich silicates, carbon and anhydrous silicates. The asteroid was discovered by Auguste Charlois on 19 September 1892 in Nice.
In 2000, the asteroid was detected by radar from the Arecibo Observatory at a distance of 1.21 AU. The resulting data yielded an effective diameter of 69 ± 9 km.
