Because of the rotation of the planet and the view.
Ellen Kim was the first to explain why the sun and stars move across the sky in 1858
stars don't move across the sky, we orbit the sun, as you should know, and as we orbit the sun we see the stars as moving but in all actuality we are just changing position and seeing the stars at a different perspective
Galileo was the first astronomer to explain why the sun and starts travel across the sky
They appear to move across the sky because of the position of the viewer on a rotating planet with a moving field of view.
The apparent movement of the sun and stars across the sky is due to the rotation of the Earth on its axis. As the Earth rotates, it gives the illusion that the sun and stars are moving across the sky from east to west. This movement is responsible for the cycle of day and night.
the sun dosent move across the sky
If by "seem to move" you are referring to perspective then it is true, since the Earth rotates on an axis and revolves around the sun, if we do not know that it is the Earth that is moving, it would seem that stars move across the sky, except for the pole star Polaris, which is aligned with the north axis and remains "fixed" in its place.
Yes, the moon appears to move across the sky from east to west, just like the sun and stars. This is due to the rotation of the Earth on its axis.
Earth rotates on its axis The moon orbits the Earth The sun IS a star so stars move the same way Earth takes a year to orbit the sun Moon takes a month to orbit the earth Earth takes a day to orbit around its axis The Sun does NOT move
The Sun doesn't: "move across the sky" Earth revolves around the Sun which is why it appears to "move across the sky".
Yes, the position of Orion in the night sky does move within an hour due to Earth's rotation. As the Earth spins on its axis, the stars appear to move across the sky, causing their positions to shift gradually over time.
He was the first person to explain why the sun and stars move across the sky
