Danaë Template:IPAc-en (minor planet designation: 61 Danaë) is a stony asteroid of the outer asteroid belt's background population, approximately 84 kilometer in diameter. It was discovered by French astronomer Hermann Goldschmidt on 9 September 1860, from his balcony in Paris, France.[1]

Goldschmidt was ill when asked to name the asteroid, and requested his fellow asteroid-hunter Robert Luther to name it instead. Luther chose to name it after Danaë, the mother of Perseus in Greek mythology.[2] Danaë was the first asteroid to have a diacritical character in its official name.

In 1985, a study of lightcurve data suggested that Danaë may have a moon. If so, the main body would be an ellipsoid measuring 85×80×75 km (52x49x46 mi), and the moon would orbit Template:Convert away, measuring 55×30×30 km (34x18x18 mi). The density of both would be 1.1 g/cm³.[1]
