Abstract The Rosetta spacecraft reached Comet 67P/Churyumov-Gerasimenko (hereafter
67P/CG) in August 2014 at an heliocentric distance of 3.6 au and was then put in orbit …

The surface geology of Jupiter's Trojan asteroids is one of the scientific investigations of the
NASA Lucy mission. A dedicated Geology Working Group will implement these studies …

Understanding how comets work—what drives their activity—is crucial to the use of comets
in studying the early solar system. EPOXI (Extrasolar Planet Observation and Deep Impact …

The factors shaping cometary nuclei are still largely unknown, but could be the result of
concurrent effects of evolutionary, and primordial processes,. The peculiar bilobed shape of …
