Introduction

The following improved orbital elements, are from 315 observations 2002 January 27 to 2014 October 12, including full planetary and non-gravitational effect of type II, and relativity effect of the sun.

The mean residual is 0.68 arc second.

Elements

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