What is precession?

Any change in the position of the axis of the rotation of the heavenly body is known as precession . Naturally, astronomical bodies contain slow changes both in their rotary speed and in an orbital state around other gravity -strong bodies. There are two types of precession in the field of astronomy: without torque and torque. According to the mathematical principles of precession without a rotating moment, the rotating axis differs from the ellipse of the object. In the case of precession induced by torque, the object maintains an alternate rotation.

The most common example of this phenomenon can be observed in the rotation of the ground itself. The axial spinning of the Earth, known primarily as Precession Equinoxes, occurs in the Earth's orbit every 25,800 years and results in a slow change in the location of the stars in the night sky. While the stars themselves do not actually change their location compared to the coordinates on the planet's surface. The observers of this shift on the Earth's crust can only identify a change in one degree every 72 years.

kRoma real changes of rotation may affect the precession changes. The inclination is basically an angle in which the astronomical body relates to a certain other body. In the case of Earth, the inclination of the planet in the solar system is essentially in accordance with Jupiter. However, this tendency will change as a result of natural driving over about 100,000 years.

The reason for changes in rotation and inclination is the oval orbit of the planets and other bodies. Gravity attracts objects towards larger objects in an imperfect way, leading to the highest rotation of the bodies. As the body spins, it causes disgusting forces against the gravitational tension, the result of the elongated orbit. The combination of these phenomena is considered to be the causes of such incidents on Earth as ice, according to the field of astronomy precession.

The first understanding of the precession was identified in 150 BC by the Hipparchus, the Greek astronomer. However, studies have shown that other ancient cultures also knew about this phenomenon, aso are the Mayans. Modern theories including the rotation and inclination of the country were set by the physical laws of Isaac Newton, who defined the effects of gravity from the sun and the moon.
