A compass is a device that is used for navigation. On holding a compass one is able to tell which direction they are facing or moving towards with the help of the arrows facing either North, South, East or West. A compass was popularly used with sailors and astronauts to navigate their way at sea and space respectively. The first compass was the magnetic compass created by the Chinese where the needle of the compass corresponds to the earth’s magnetic field.
To this date, compasses are used. Even the GPS that we know of and use today, uses a compass to navigate.
