Celestial navigation

Celestial navigation is a way of finding your way on a boat or ship by using the sun, stars, and moon. It helps you to know what direction you need to go in and how far away you are from certain places. To do this, sailors use special instruments like a sextant and a compass. With a sextant, they measure the angle between two stars in the sky. By knowing the kind of stars and where they are in the sky, sailors can figure out where they are on the map. With a compass, sailors point the arrow toward the North Star which helps them know what direction to go in.
