228 Agathe is a small main belt asteroid. It was discovered by Johann Palisa on August 19, 1882 in Vienna and named after the youngest daughter of Austrian astronomer Theodor von Oppolzer.[1] 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.[2]
