208 Lacrimosa is a Main belt asteroid. It is classified as an S-type asteroid.
It is also one of the largest members of the Koronis asteroid family and probably a piece of the original asteroid which was shattered in an ancient impact that created the family.
It was discovered by 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.
