473 Nolli is a rather small asteroid that may be in the Eunomia family. It was discovered by Max Wolf on February 13, 1901, but only observed for 1 month^[2] so it became a lost asteroid for many decades. It was recovered in 1987 86 years later.,^[4] Almost nothing is known about its characteristics.
