442 Eichsfeldia is a large Main belt asteroid. It is classified as a C-type asteroid and is probably composed of primitive carbonaceous material.
It was discovered by Max Wolf and A. Schwassmann on February 15, 1899 in Heidelberg.
Although Eichsfeldia has an orbit similar to the Vesta family asteroids, it was found to be an unrelated interloper on the basis of its non-matching spectral type.
