228 Agathe
228 Agathe is a stony main belt asteroid, about 9 kilometers in diameter. It was discovered by Johann Palisa on August 19, 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.〔 Agathe was named after the youngest daughter of Austrian astronomer Theodor von Oppolzer (1841–1886), professor of astronomy in Vienna.〔 == References ==
