473 Nolli is a medium-sized asteroid. It was discovered by Max Wolf on February 13, 1901, but unusually it remained lost for many decades, until it was recovered finally in 1987 ^{[http://cfa-www.harvard.edu/iauc/04200/04292.html#Item1]} , 86 years later. Almost nothing is known about its characteristics.
