Abstract We have derived a tri-axial ellipsoidal model of an LEO object, a Cosmos 2082 rocket body, including its rotational axis direction, rotation period, precession, and a compositional parameter, using only light curve data from an optical telescope. The brightness of the object was monitored for two days and least-squares fitting was used to determine these values. The derived axial ratios are 100:18:18, the coordinates of the rotational axis direction on the celestial sphere are R.A. =305.8° and Dec. =2.6°, and its observed average rotation period is 41s. When precession is considered, its amplitude and precession period are 30.5° and 29.4min. These results show that optical light curve data are sufficient to determine the shapes and the motions of LEO objects.
