WithdrawnNewer orbit data from 26 Oct 12:45 UTC no longer shows this pass. Within 40 minutes of the predicted time the two stayed at least 16.0 km apart. The most recent pass the screening confirmed up to its time: 5.41 km on 27 Oct 06:13 UTC.
USPROJECT SUNCATCHER M1 and TBDOBJECT CK were predicted to reach a closest approach of 8.48 km at 2026-10-26 21:38 UTC, drifting past at about 3.0 m/s (11 km/h) as seen from OBJECT CK. Withdrawn: newer orbit data from 26 Oct 12:45 UTC no longer shows this pass. Within 40 minutes of the predicted time the two stayed at least 16.0 km apart. The figure above is the forecast as it was published; the newer check is shown beside it, and nothing is overwritten. Miss distance and time of closest approach are computed by propagating the latest published orbital elements for both objects, and each pass is re-checked every 20 minutes as new element sets are published. See the Satellite Maneuver Tracker for the live picture and space situational awareness for context.
Why it mattersBoth objects are catalogued as payloads. Screening continues as new element sets arrive; operators act on their own conjunction data.
At 510 km this pass sits in low Earth orbit. Objects here stay up for decades: there is too little atmospheric drag to clean the band naturally. Why crowded bands matter →

Repeat encounters are common for objects in near-intersecting orbital planes. Each pass is re-screened as fresh element sets arrive; "Final forecast" means the screening still predicted it within 45 minutes of its time, "Not re-confirmed" means later screening stopped finding it.

Every figure published for the pass shown above, newest first. Nothing is overwritten: a withdrawn forecast keeps its figure, with the newer check beside it, and the best estimate after the pass is a row of its own.

Miss distance and TCA come from propagating the latest published orbital elements for both objects and searching for the minimum separation over the screening window. Element sets carry kilometre-scale uncertainty, so figures here describe a close pass, not a collision prediction; a change in either object's published elements re-computes the pass automatically.
