336 Lacadiera
Lacadiera (minor planet designation: 336 Lacadiera) is a large Main belt asteroid.[1] 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.
