Description

The brightness of satellites as observed from Earth varies significantly with orbital parameters and solar angle, with the brightest satellites leaving trails across astronomical images. This work explores how a satellite's altitude, inclination and structure, as well as the observer's position, affects the apparent brightness of the satellite. Using a rudimentary ray-tracing model that incorporates these parameters, we discuss the various orbital regions and local times of day when satellite brightness is minimised for astronomical observations.
