208 Lacrimosa is a main-belt asteroid that was discovered by Austrian astronomer Johann Palisa on October 21, 1879, in Pola. The name derives from Our Lady of Sorrows, a title given to Mary, the mother of Jesus.
10µ radiometric data collected from Kitt Peak in 1975 gave a diameter estimate of 42 km for this asteroid. It is classified as an S-type asteroid and is one of the largest members of the Koronis asteroid family. Hence it is probably a piece of the original asteroid that was shattered in an ancient impact that created the family.
