206 Hersilia is a fairly large Main belt asteroid. It was discovered by C. H. F. Peters on October 13, 1879 in Clinton, New York. The asteroid was named after Hersilia, Roman wife of Romulus. It is classified as a primitive, dark carbon-rich C-type asteroid.

Measurements made with the IRAS observatory give a diameter of 101.72 ± 5.18 km and a geometric albedo of 0.06 ± 0.01. By comparison, the MIPS photometer on the Spitzer Space Telescope gives a diameter of 97.99 ± 7.40 km and a geometric albedo of 0.06 ± 0.02.[1]
