The motion of Eros' rotation axis in space.
Abstract
A calculation of the coordinates of the poles of Eros from observational data shows that the direction of Eros' rotation has undergone considerable change due to nutation in a time scale of one month. The theoretical amplitudeaspect relation is compared with the actual relation corresponding to various poles. The length of Eros is computed to be about 22 kilometers. Eros is rotating counterclockwise as seen from its north pole; therefore, it is rotating directly.
