SOLAR SYSTEM

Detailed explanation-1: -The Earth orbits the sun once every 365 days and rotates about its axis once every 24 hours. Day and night are due to the Earth rotating on its axis, not its orbiting around the sun.

Detailed explanation-2: -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. Mean solar time represents an average of the variations caused by Earth’s non-circular orbit.

Detailed explanation-3: -Together with its revolution around Sun, the Earth also rotates around its own axis. This rotation of Earth causes day and night. Earth’s side facing Sun experiences day and the other side facing away from the Sun experiences night.

Detailed explanation-4: -The rotation of the Earth on its axis causes day and night. As the Earth rotates, only one-half of the Earth faces the sun at any given time. The half facing the sun is light (day) and the half facing away from the sun is dark (night). The animation below shows the Earth’s rotation.
