101249 (1998 SQ89) — orbit, source & time explorer

A dated view of a changing orbit

This record uses JPL solution JPL 31, with element epoch JD 2461200.5 TDB. Its osculating eccentricity is 0.166351, inclination 4.49374°, and perihelion distance 2.16388 AU. These describe an instantaneous fitted conic; planetary encounters can change the future orbit.

The explorer evaluates a two-body overview at the selected date. A bounded Horizons vector request offers a separate source-calculated path. The two models can disagree, especially during encounters and far from the element epoch.

What the measurements support

Observation arc: 12919 days; observations used: 818. Orbit condition code: 0. A short observation arc can leave a future path poorly constrained.

Published diameter: not available. Rotation period: not available. Unknown values remain unknown. Generic shape and exaggerated display size are visual aids, not measurements of this object.

Inspect it yourself

Begin with the source epoch, pause the clock, then tilt the camera to inspect the orbital plane. Use Focus or Follow to keep the object in view. For an encounter, switch to Events and load the JPL trajectory instead of interpreting an orbit crossing as a close approach.

Future paths are predictions from a particular solution. Tuduni does not infer impact probabilities or confidence envelopes from an illustrative curve.
