Introduction

The following improved orbital elements, are from 213 observations 1950 June 18 to 2010 February 12. Perturbations by all nine planets were taken into account, and relativity effect of the sun.

The mean residual is 0.44 arc second.

Elements

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