Conjunctions Database
A database of conjunction data messages, collecting information about orbital traffic. It tracks assets which could impact with debris or other satellites in their trajectory and it reports probability of collision as well as minimum ranges at the time of closest approach between the objects.
No filters applied. Showing all conjunctions.
Interactive space conjunctions data charts
Daily conjunctions in space
An overview of the number of conjunctions registered per day.
Conjunctions by object type
A classification of conjunctions by type. Filtering by object type is available.
Conjunctions overview
Mapping of conjunctions with an estimated miss distance under 1000 [m] and a probability of collision above 1 in 10'000 (i.e. > 0.01%).
