CN HULIANWANG DIGUI 232 and CN HULIANWANG DIGUI 235 were predicted to reach a closest approach of 4.10 km at 2026-11-12 18:17 UTC, drifting past at about 6.9 m/s (25 km/h) as seen from HULIANWANG DIGUI 235. Withdrawn: newer orbit data from 11 Nov 21:50 UTC no longer shows this pass. Within 40 minutes of the predicted time the two stayed at least 399.9 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.
The Two Objects
Where This Happens
At 926 km this pass sits inside the most congested band in low Earth orbit, home to the debris left by the 2007 ASAT test and the 2009 collision. Objects here stay up for decades: there is too little atmospheric drag to clean the band naturally. Why crowded bands matter →
History Between This Pair
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.

How These Numbers Are Computed
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.
