Rosetta's Trajectory
Rosetta's Trajectory Being solar powered, Rosetta had to hibernate when it reached 4.5 AU in June 2011. After waking, it rendezvoused with 67P on 6 August 2014 and accompanied the comet through its changing seasons and perihelion passage until the mission was brought to an end on 30 September 2016. Distances are given with respect to the comet surface. Emily Lakdawalla and Loren A. Roberts for The Planetary Society
