In what direction does Polaris always hang high?

Polaris is always high in the north of the sky.

Polaris, also known as Beichen and Zixing, refers to the star closest to the North Celestial Pole. At present, it refers to "Gou Chen Yi". Polaris is located at the northern end of the earth's axis, which is five times as long as the extension line connecting Tian Xuan and Shu Tian in the Big Dipper. Because of the rotation of the earth, and Polaris is on the axis of celestial rotation, the observer is stationary relative to the ground.

Polaris is about 323 to 434 light-years away from the earth and has a diameter of about 52 million kilometers. "Gouchenyi" consists of three celestial bodies: Polaris Aa, Polaris B and Polaris Ab. The main star Polaris A is a huge, bright and yellow Supergiant star. Polaris A is 4.5 times the mass of the sun, and if it is placed with the sun, its brightness is 1260 times that of the sun.

Polaris is a bright star in the northern part of the sky, very close to the north celestial pole, almost facing the earth axis. Seen from the northern hemisphere of the earth, its position is almost unchanged, so it can be used to identify the direction. Because of the rotation of the earth, Polaris is just on the axis of celestial rotation, so it is relative to other stars.

However, the Polaris is not completely at the center of the north celestial pole. In fact, it is circling at a very slow speed, and looks unchanged compared with other stars. Polaris is motionless, because the earth revolves around the earth axis, and Polaris is very close to the northern extension line of the earth axis, so when you look at the sky at night, Polaris is almost motionless.

And it is northbound, so it can indicate the north. Although the tilt direction of the earth's axis will change because the earth revolves around the sun all year round, the distance between Polaris and the earth is much larger than the radius of the earth's revolution, so the change of the earth's axis brought about by the earth's revolution can be ignored.
