Rosetta tracks debris around comet
Paris (ESA) Jun 25, 2015
In two papers, accepted for publication in Astronomy and Astrophysics, scientists provide an update on their study of debris around the comet. The studies are reported in "Orbital elements of material surrounding comet 67P/Churyumov-Gerasimenko" by B. Davidsson et al, and "Search for satellites near comet 67P/Churyumov-Gerasimenko using Rosetta/OSIRIS images" by I. Bertini et al. Ever since its approach to and arrival at Comet 67P/Churyumov-Gerasimenko, Rosetta has been investigating the nucleus a ... read more
