Introduction

The following improved orbital elements, are from 130 observations 1975 October 27 to 2011 March 23. Perturbations by all nine planets were taken into account, and relativity effect of the sun.

The mean residual is 0.69 arc second.

Elements

Orbital elements given with respect to the mean ecliptic and equinox of J2000.
