Lacrimosa (minor planet designation: 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. It is orbiting the Sun at a distance of 2.89320 AU with a period of 4.92 yr and an eccentricity (ovalness) of 0.013. The orbital plane is inclined at an angle of 1.7° to the plane of the ecliptic.[1]

During 2003, the asteroid was observed occulting a star. The resulting chords provided a cross-section diameter estimate of 44.3 km.[3] 10μ radiometric data collected from Kitt Peak in 1975 gave a diameter estimate of 42 km for this asteroid.[4] It is classified as an S-type asteroid and is one of the largest members of the Koronis asteroid family.[5] Hence it is probably a piece of the original asteroid that was shattered in an ancient impact that created the family.
