This is the largest canyon system known in the solar system. The entire canyon system is some 4000 kilometres long,200 kilometres wide and up to 7 kilometres deep. Phobos is irregular in shape,measuring 19 by 21 by 27 kilometres. It orbits 9400 kilometres above Mars,taking just over 7.6 hours to complete an orbit.
