Abstract
Discrete particle ejection events are known to periodically occur on the asteroid Bennu. Similar
phenomena may also occur on other small bodies in our Solar System. If these particle
events are observed by the camera aboard an exploration spacecraft, as was the case with
the OSIRIS-REx spacecraft during its visit to Bennu, then the apparent motion of particles
may be used to reconstruct the event. This work explores the utility of algebraic projective
geometry for performing this reconstruction and the resulting algorithms are shown to
have many practical advantages when compared to earlier methods. The algorithms are further
tested through numerical simulation, including cases with varying numbers of particle
observations.
