    Vindobona (minor planet designation: 231 Vindobona) is a large Main belt asteroid. It was discovered by Austrian astronomer Johann Palisa on September 10, 1882. Vindobona is the Latin name for Vienna, Austria, the city where the discovery was made.

    Its dark surface indicates a carbon-rich composition.

    Photometric observations at the Organ Mesa Observatory in New Mexico during 2012 showed a rotation period of 14.245 ± 0.001 hours with a brightness variation of 0.20 ± 0.03 in magnitude. This is in agreement with previous results. [3]

    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. Agathe is the lowest numbered asteroid to have an Earth-MOID as low as 0.657 AU (98.3 million km). On 23 August 2029 the asteroid will be 0.659 AU (98.6 million km) from Earth.
