Open 424P/La Sagra in the live scene → The scene composes a position for any date and is where a figure becomes a picture. It downloads the whole catalogue first: measured against the built product, an object outside the core resolves after about 16 s over a local network and about 147 s over a 4 Mbit link, having transferred roughly 70 MB. If you cannot wait that long, this page is the answer.
These are the sourced elements. This page does not print a position: a position is a function of time, and a single one dated to the bake would be stale the moment it was read. The registry composes a position for any date, past or future, from these elements — open the scene below and set the clock.

Elements are expressed in the frame of
SOL at epoch
2016-05-02 00:00:00 UTC (JD 2457510.5). Gravitational parameter of the primary:
1.3271244×10^20 m³/s². Semi-major axis in astronomical units uses the
IAU 2012 definition (1 au = 1.495978707×10^11 m exactly).

| Coverage | 1417 bound periodic comets incl. 1P/Halley; heliocentric osculating elements at per-row epoch; hyperbolic/parabolic (single-apparition) comets excluded — no invented ellipse (A5); radius only where SBDB measures a nucleus diameter (104). 1417 of 1417 carry their JPL orbit solution; 1128 of those carry an MPC U value (long-period comets are classified by orbit QUALITY codes instead, a different scale, not mapped onto U). Each object carries its JPL orbit solution: observations used, arc, residual rms, producer and the MPC uncertainty parameter U (0-9), whose in-orbit longitude runoff band is derived from the MPC's published definition. The MPC states that "the U value should not be used as a predictor for the uncertainty in the future motion of NEAs" — it classifies the SOLUTION, not the future. The published 6x6 covariance is deliberately NOT carried: it is stated at the solution epoch, a median 2,994 days from the epoch of the elements served here (measured over a 45-object sample), and transporting a correlated uncertainty across that gap needs JPL's own force model, which this registry does not have. |
