The North Star (aka Polaris) is famous for holding nearly still in our sky while the entire northern sky moves around it. That’s because it’s located near the north celestial pole, the point around which the entire northern sky turns. Polaris is not the brightest star in the nighttime sky, as is commonly believed. It’s only about 50th brightest but is the brightest star in the constellation Ursa Minor.
A star trail is a type of photograph that utilizes long-exposure times to capture the apparent motion of stars in the night sky due to the rotation of the Earth. Star trail photographs are possible because of the rotation of the Earth on its axis. The apparent motion of the stars is recorded as streaks. For photographers in the northern hemisphere, aiming the camera towards the north creates an image with concentric circular streaks centered around the north celestial pole. The North Star sits near the point of rotation for the axis of the Earth directly above the North Pole.
