*As the number of artificial satellites orbiting our planet grows, the likelihood of collisions increases, potentially triggering a cascade effect making certain orbits unusable.*

**cascade** is a C++/Python library developed to propagate the evolution of large number of orbiting objects

while detecting reliably close encounters and collisions. It is coded in modern C++20 with focus on the

efficency of the underlying N-body simulation with collision/conjunction detection. Its development was

motivated to help conjunction tracking and collision detection of orbiting space debris populations.

Notable features include:

* an original collision detection algorithm exploiting high order Taylor expansions.

* guaranteed detection of all occuring collisions and conjunctions.

* high precision orbital propagation via Taylor integration.

* possibility to define custom dynamics.

* seamless usage of modern SIMD instruction sets (including AVX/AVX2/AVX-512/Neon/VSX).

* seamless multi-threaded parallelisation.
