Introduction

The following improved orbital elements, are from 242 observations 1998 May 24 to 2009 March 24. Perturbations by all nine planets were taken into account, and relativity effect of the sun.

The mean residual is 0.75 arc second.

Elements

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

Formulæ for magnitudes

Total magnitude :
m₁ = H₁ + 5log(Δ) + 10 log(r) avec H₁ = 11.63± 0.05 calculé à l'aide de 112 observation(s).
Nuclear magnitude :
m₂ = H₂ + 5log(Δ) + 5 log(r) avec H₂ = 14.39±0.04 calculé à l'aide de 41 observation(s).
