Phase-ratio imagery of 67P/Churyumov-Gerasimenko at small phase angles using Rosetta-OSIRIS images
Abstract
The Rosetta spacecraft reached its target 67P/Churyumov-Gerasimenko (hereafter 67P) in July-August 2014 and orbited around the comet until 30th September 2016. During the 2.5 years of mission, Rosetta did two zero-phase-angle fly-bys: the spacecraft was flying between the Sun and the comet and therefore, the angle between the Sun and the observer (known as phase angle, α) approached zero. In this phase angles range, a phenomenon, known as, opposition effect, manifests itself as a rapid increase in the surface brightness.
