On 2026-09-25 00:17 UTC, RU COSMOS 2493 (SKRL 756) and BRAZ ICEYE-X39 reached a closest approach (TCA) of 5.12 km, with a relative velocity of 15.15 km/s. Miss distance and time of closest approach are computed by propagating the latest published orbital elements for both objects, and values update 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 561 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 →
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.

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.
