In view of the high value of space assets and a growing space debris population, collision analysis is of great significance. Collisions between space objects can, at best, be determined in a probabilistic manner. Collision probability between objects is closely related to close approaches of the objects, where the traditional approach to determining the collision probability is predicated upon finding a time of closest approach and bounding this with a deterministic time interval. This paper investigates the application of information theory to the determination of a conjunction interval. Cases of two and more-than-two objects in close proximity are considered, and methods for determining the interval in which the objects are interacting are developed. Simulations are carried out to compare the developed methods to more conventional techniques.
