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

Epoch (TT) 17031021
time of perihelion passage (TT) 20021120.348184 ± 0.000045
perihelion distance 1.25026531 ± 0.00000022
eccentricity 0.99994161 ± 0.00000138
argument of perihelion [deg] 133.240735 ± 0.000044
longitude of the ascending node [deg] 33.718928 ± 0.000043
inclination [deg] 149.330682 ± 0.000012
inverse semimajor axis [10-6 au-1] 46.70 ± 1.10

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.
