To extrapolate to future times, the following heliocentric IAU76 J2000
ecliptic osculating elements can be manually input into Horizons as starting
conditions for a ballistic numerical integration using the telnet or e-mail
interfaces:
EPOCH = 2440561.50 ! A.D. 1969-Dec-06 00:00:00.0 (TDB)
EC= 3.788077679293159E-02 QR= 9.895270525906216E-01 IN= 5.742003975916762E-02
OM= 3.492340571440683E+01 W = 4.664715199038439E+01 Tp= 2440569.022123539820
... where
EPOCH Epoch Julian Day Number, Barycentric Dynamical Time
EC Eccentricity, e
QR Periapsis distance, q (au)
IN Inclination w.r.t xy-plane, i (degrees)
OM Longitude of Ascending Node, OMEGA, (degrees)
W Argument of Perifocus, w (degrees)
Tp Time of periapsis (Julian Day Number)
Uncertainties and errors in the extrapolated position prediction will increase
as the time from the EPOCH increases. Predictions for this man-made object
years past the EPOCH are problematic due to unmodeled-but-cumulative solar
pressure and out-gassing accelerations, yet no further tracking data to
characterize the forces.
Supplemental orbital elements (FYI, at same epoch):
N = 9.449436351342855E-01 MA= 3.528920172383751E+02 TA= 3.523284678961845E+02
A = 1.028486936673184E+00 AD= 1.067446820755747E+00 PR= 3.809751043498384E+02
... where
N Mean motion, n (degrees/day)
MA Mean anomaly, M (degrees)
TA True anomaly, nu (degrees)
A Semi-major axis, a (au)
AD Apoapsis distance (au)
PR Sidereal orbit period (day)
