The stars are described as 'fixed', which means they all appear to go round on a fixed sphere every 24 hours. Each star stays in the same direction (very nearly) for many years at a time. But the planets go round the Sun, just as we do, so they appear in different directions as they go round.
But because they all go round in a plane (approximately), like a big thick saucer with the Sun at the centre, they all appear to move round a circle in the sky called the ecliptic. Each planet gets round the ecliptic once in the time it takes to go round the Sun. Because the orbits are slightly inclined, the planets do not always stick exactly on the ecliptic but they are never far off it.

∙ 10y agoThe Stars appear `fixed` as seen from earth, but the planets are much closer
and are in varying orbits around our sun. Our own planets orbit, as well as
the other planet movements, mean that the relative positions of these planets
are seen to change over time against the background stars.

It is now known that the celestial objects which appear to move backwards among the stars are?
Planets
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.
How are planets distinguished from stars on the celestial?
planets appear to move
What direction did Regulus move across the sky from?
Regulus stars appear to move across the sky from East to West (:
Explain why stars appear to move across the sky each night why are some stars only visible doing certain seasons?
Stars appear to move across the sky each night because the earth is moving, but not the stars. Also some stars are only visible during certain seasons because as the earth rotates, they become visible.

Do stars appear to wander off their star paths?
stars dont move, but as we move they appear to.
Which is the wandering planet?
All the planets move continuously among the fixed stars, so they were called the wandering stars.The planets all move in or near a fixed plane. As they wander they all appear to stay close to the plane of the Earth's orbit, which is the ecliptic.
Why planet are called planet?

Do the stars and the and sun move 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.
Do stars move as much as the moon?
Stars do not move, but the moon orbits. Stars appear to move because we are moving.
In which direction do the stars appear to move?
In the northern hemisphere they appear to move counter clockwise; In the southern hemisphere they appear to move clockwise.
Why do stars and constellation appear to move in the night sky?
Stars and constellations appear to move in the night sky because the Earth is rotating, while the stars and constellations stay there.
The stars appear to move across the sky at night is this true?
YES!!! Because '- #1 the Earth is rotating so it appears that the stars move across the sky. #2 the Stars in their own right also move. Since most stars are so far away their movement is hard to detect. #3 the Planets, appear to be stars, because they are pin point spots of light. The planets move , notably Venus, which can be seen as the Morning Star, or at a different time of the year as the Evening Star. The word 'planet' comes from Classical Greece, and means 'Wandering Star'.
How do planets move in relation to stars?
They mostly appear to move from east to west but there are epicycles during wich they appear to move from west to east.
When you view the stars and planets in the night sky they all appear to move on a great?
They appear to move on a great hollow sphere
Which star do not appear to move from east to west?
During roughly half of the time, 'circumpolar' stars don't appear to move from east to west. Which ones those are depends on your latitude. All other stars all the time, and circumpolar stars for the other half of the time, do appear to move from east to west.
