Original: The initial orbit estimate of the recently discovered satellite S\/2000 J 11 also qualified it as a member of the group ( it appeared to have the same inclination , and a slightly larger semi-major axis ) but its orbit is not known with adequate precision and the mean orbital elements have not yet been calculated .
Simplified: The orbit estimate of the recently found moon S\/2000 J 11 also qualified it as a member of the group ( it appeared to have the same inclination , and a slightly bigger semi-major axis ) but its orbit is not known exactly and the mean orbital elements have not yet been calculated .
