RU COSMOS 2114 and US THORAD DELTA 1 DEB are predicted to reach a closest approach of 1.87 km at 2026-11-05 08:58 UTC, at a relative speed of 14.04 km/s. Confirmed by the latest screening, 5 Nov 02:12 UTC. This is a cross-border encounter between objects of different nations, the kind of event closely watched for space-security implications. 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 1404 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 →
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.
