Original orbital elements (barycentric; at 250 au from the Sun)

Epoch (TT) 16980429
time of perihelion passage (TT) 20000919.495624 ± 0.000779
perihelion distance 2.92741701 ± 0.00001356
eccentricity 0.99977040 ± 0.00000577
argument of perihelion [deg] 284.863084 ± 0.000357
longitude of the ascending node [deg] 49.766597 ± 0.000013
inclination [deg] 104.117932 ± 0.000083
inverse semimajor axis [10-6 au-1] 78.43 ± 1.97

Note: Values of uncertainties of original/future orbital elements were derived using a swarm of 5001 osculating orbits of VCs (including the nominal osculating orbit given above) for original/future orbital evolution calclulations and then by fitting the distribution of a given orbital element of original/future swarm of VCs to Gaussian distribution.

Original barycentric positions and velocities of 5001 VCs at 250 au from the Sun are given here   (data format), i.e. before entering the planetary zone.
