Introduction

The following improved orbital elements, are from 277 observations 1999 August 17 to 2013 February 10. Perturbations by all nine planets were taken into account, and relativity effect of the sun.

The mean residual is 0.35 arc second.

Formulæ for magnitudes

Total magnitude :
m₁ = H₁ + 5log(Δ) + 10 log(r) avec H₁ = 13.57± 0.03 calculé à l'aide de 151 observation(s).
Nuclear magnitude :
m₂ = H₂ + 5log(Δ) + 5 log(r) avec H₂ = 15.40±0.03 calculé à l'aide de 57 observation(s).
