The compass is an instrument that points to the Earth’s North Pole. On Earth we can use a compass to guide us because the needle points to the approximate position of the North Pole.
The compass face also shows the South Pole, which is in the opposite direction to North, as well as the position of the Sun at sunrise and sunset. The Sun rises in the East and sets in the West.
