The comet 67P/Churyumov-Gerasimenko has small cliffs that stretch across the landscape for months at a time.

The European Space Agency’s Rosetta spacecraft has provided amazing images of the comet. Its truly incredible to see boulders which look so familiar on a comet. One could imagine walking through the various pathways exploring each section of rock. 

See this incredible video from the Agency

 

Rosetta arrived at 67P in 2014 and orbited the comet for two years. The pictures show a changing landscape. When the comet approached the sun, dust and gas were seen fired off from the surface into space.
