71 Niobe[b] is a stony Gallia asteroid and relatively slow rotator from the central regions of the asteroid belt, approximately 90 kilometers (56 miles) in diameter. It was discovered by the German astronomer Robert Luther on 13 August 1861, and named after Niobe, a character in Greek mythology. In 1861, the brightness of this asteroid was shown to vary by astronomer Friedrich Tietjen.[22]
