228 Agathe is a stony main belt asteroid, about 9 kilometers in diameter. It was discovered by Johann Palisa on 19 August 1882 at Vienna Observatory, Austria. Photometric observations during 2003 showed a rotation period of 6.48 ± 0.01 hours with a brightness variation of 0.27 ± 0.03 in magnitude. An earlier study yielded results that are consistent with these estimates.[1] Agathe is the lowest numbered asteroid to have an Earth-MOID as low as Script error: No such module "convert"..[2] On 23 August 2029 the asteroid will be Script error: No such module "convert". from Earth.
