SOLAR SYSTEM

Detailed explanation-1: -From Earth, the Sun looks like it moves across the sky in the daytime and appears to disappear at night. This is because the Earth is spinning towards the east. The Earth spins about its axis, an imaginary line that runs through the middle of the Earth between the North and South poles.

Detailed explanation-2: -Answer: The rotation of the Sun is due to conservation of angular moment. What this means is that the gas cloud from which the Sun formed had some residual angular momentum that was passed-on to the Sun when it formed, which gives the Sun the rotation that we observe today.

Detailed explanation-3: -Earth’s rotation on its axis occurs every 24 hours. As Earth rotates, it seems like the sun is moving across the sky, but it’s really the Earth that is spinning. It takes 24 hours to complete one rotation, which is why there are 24 hours in one day.

Detailed explanation-4: -As Earth rotates on its axis, the different locations on Earth change position in relation to the Sun. A city on Earth that faces toward the Sun at noon will rotate to face away from the Sun 12 hours later. The positions of Earth and the Sun over the course of a 24-hour rotation cause sunrise, sunset, day, and night.

Detailed explanation-5: -Earth rotates or spins toward the east, and that’s why the Sun, Moon, planets, and stars all rise in the east and make their way westward across the sky.

Detailed explanation-6: -In fact, it is Earth’s rotation that causes the Sun’s apparent motion. Earth rotates from west to east. This makes the Sun appear to move from east to west across the sky. The Moon and stars also seem to move from east to west across the sky due to Earth’s west-to-east rotation.
