208 Lacrimosa is amain-beltasteroid that was discovered by Austrian astronomerJohann Palisa on October 21, 1879, inPola. The name derives fromOur Lady of Sorrows, a title given toMary, the mother of Jesus. It is orbiting theSun at a distance of2.89320 AU with aperiod of 4.92 yr and aneccentricity (ovalness) of 0.013. Theorbital plane is inclined at an angle of 1.7° to theplane of the ecliptic.[1]
During 2003, the asteroid was observedocculting a star. The resultingchords provided a cross-section diameter estimate of 44.3 km.[3] 10μ radiometric data collected fromKitt Peak in 1975 gave a diameter estimate of 42 km for this asteroid.[4] It is classified as anS-type asteroid and is one of the largest members of theKoronis asteroid family.[5] Hence it is probably a piece of the original asteroid that was shattered in an ancient impact that created the family.
