Why do planets appear in different locations in the night sky while stars in a constellation stay in the same place?
Because the stars are very far away and are suns like our Sun. The planets however are in orbit round our Sun and relatively close to us. We can therefore see the movement of their orbit against the background of the "fixed" stars.
Why do all stars appear to move except the pole star?
All stars appear to move due to Earth's rotation, but the Pole Star, also known as Polaris, remains in a relatively fixed position in the sky because it is located almost directly above Earth's North Pole. This causes it to appear stationary as other stars appear to rotate around it.
Why planet are called planet?
Planet comes from an ancient Greek term meaning 'wanderer'. They were called wanderers because they appear to move against the apparent stationary background of stars.
Why are planets also called as wanderers?
The very first astronomers merely looked at night at the stars. They noticed that almost all the stars circled the north star (Polaris) during the night (this is due to the Earth's rotation). Some of the stars seemed to be moving differently, with paths of their own, these were not stars, but were planets.
If the earth is spinning why aren't the stars blurry?
The stars appear fixed in the sky because they are extremely far away from Earth. The motion of Earth's rotation is not fast enough for the stars to blur in our view over the course of a night. Additionally, the human eye is not sensitive enough to detect this motion.

Why do planets change their position with respect to stars?
Because the Earth and all the planets move in orbits round the Sun, while the stars appear to be fixed if we disregard the Earth's daily rotation.
From the northern hemisphere circumpolar stars appear to be circling what?
From the northern hemisphere, circumpolar stars appear to be circling around the North Star, also known as Polaris. This is because the North Star is located near the North Celestial Pole, making it a fixed point in the sky around which the circumpolar stars appear to revolve.
Why do all stars appear to move except the pole star?
All stars appear to move due to Earth's rotation, but the Pole Star, also known as Polaris, remains in a relatively fixed position in the sky because it is located almost directly above Earth's North Pole. This causes it to appear stationary as other stars appear to rotate around it.
What star is considered fixed star?
All the visible stars are considered fixed stars to distinguish them from the planets that wander round among the fixed stars. Some nearby stars appear to move very slowly with what is called 'proper motion'; but it takes thousands of years for the shapes of the constellations to change even slightly.
Why do the sun and planet appear to be moving through fixed stars?
The Sun and orbiting planets are MUCH closer to the Earth than other stars.
Which is a fixed star the sun the Proxima Centauri or the pole star?
Any star other than our own sun is a fixed star. Therefore Proxima Centauri (a red dwarf star) and the Pole Star (Polaris) are fixed stars. Note that fixed stars only appear to be fixed but are actually in motion.
How can stars remain in the same position in the sky?
Stars all appear to revolve around the sky each day as the Earth revolves, but relative to each other the stars stay 'fixed'. That is because they are so distant it takes years for any of them to move appreciably.
Why planet are called planet?
Planet comes from an ancient Greek term meaning 'wanderer'. They were called wanderers because they appear to move against the apparent stationary background of stars.
Are stars the only fixed objects in the galaxy?
No. Stars are not fixed objects.

Some of the stars seemed to be moving differently, with paths of their own, these were not stars, but were planets.
The planets appear to move through the background of stars because?
the planets orbit the Sun at varying speeds, causing them to appear to move against the fixed backdrop of stars as seen from Earth. This apparent motion is due to the Earth's own movement around the Sun, which creates the illusion of planets traversing the sky over time.
