SOLAR SYSTEM

Detailed explanation-1: -It takes Earth’s axis about 26, 000 years to complete a circular “wobble.” This wobble is called axial precession. Earth’s axis helps determine the North Star, and axial precession helps change it. Currently, for instance, Earth’s axis points toward a star called Polaris.

Detailed explanation-2: -Precession – the direction of the axis (26, 000 year cycle) This motion occurs due to the tidal forces exerted by the Moon and the Sun on the Earth. The impacts of precession are largely felt at perihelion (when the Earth is at its closest proximity to the Sun) due to increased solar radiation.

Detailed explanation-3: -Earth’s Precession. The gravitational pull of the Sun and Moon on Earth’s equatorial bulge causes Earth’s rotational axis to gyrate around the vertical, tracing a cone in space over a period of 26, 000 years.

Detailed explanation-4: -Earth’s Rotation The Earth rotates on its axis relative to the sun every 24.0 hours mean solar time, with an inclination of 23.45 degrees from the plane of its orbit around the sun.

Detailed explanation-5: -It spins on an axis that is tilted 23 and a half degrees to the plane of its orbit. This axial tilt remains steady throughout the year. Depending on the time of year, some parts of the Earth are tilted more toward the direct rays of the Sun than others.
