Introduction

The following improved orbital elements, are from 1074 observations 1984 March 2 to 2010 June 7, including full planetary and non-gravitational effect of type II, and relativity effect of the sun.

The mean residual is 0.43 arc second.

Elements

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

A₂ = 0.00271 .10^-8 ±0.00011 .10^-8

Formulæ for magnitudes

Total magnitude :
m₁ = H₁ + 5log(Δ) + 10 log(r) avec H₁ = 12.85± 0.03 calculé à l'aide de 300 observation(s).
Nuclear magnitude :
m₂ = H₂ + 5log(Δ) + 5 log(r) avec H₂ = 14.48±0.01 calculé à l'aide de 489 observation(s).
