 Gaspra's rotational axis has been determined to point in the direction of RA 0h 40m, declination 27 ± 2°.This is equivalent to ecliptic coordinates (β, λ) = (21°, 20°) and gives an axial tilt of 72°.The Galileo flyby was too distant for a body of Gaspra's small size to noticeably affect Galileo's trajectory, so no information on Gaspra's mass was obtained.
