Diemos, the smaller of the two moons of Mars, takes 30.3 hours to make one orbit of Mars.
It takes Mars approximately 687 Earth days to orbit the sun once. This is equivalent to about 16,494 hours.
Mars has two moons called Phobos and Deimos that orbit round it. Phobos goes round in 11 hours, which is faster than Mars rotates so it rises in the west and sets in the east, while Deimos takes 30 hours but seems to take about 5½ days to go round as seen from Mars's surface.
