Why do planets appear to move through the background of stars?

Planets appear to move through the background of stars because they orbit the Sun at different speeds. As the Earth and other planets move in their orbits, their positions relative to the background stars change, causing them to appear to move across the sky. This is known as planetary motion.


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'.


Why do planets wander?

The ancient Greeks called planets 'wanderers' because they appear to move through ther skies in relation to the 'fixed' stars. The apparent movement is because the planets are much closer to the Earth than the stars, and all planets rotate around the Sun, thus all move in relation to each other.


Why do patterns of stars in the sky stay the same although they appear to move across the sky nightly?

The patterns appear the same because the stars are so far away that their movement is not apparent to our eyes. They move across the sky because the earth is rotating and that makes it look like the stars are moving. Just like the sun does not move across the sky, the earth rotates and the sun appears to move, the same is with the stars.


The strip of the sky through which the sun the moon and the brightest planets appear to move in the course of a year is called what?

The strip of the sky through which the sun, moon, and brightest planets appear to move in the course of a year is known as the ecliptic.

Planets naturally move in our sky over time and therefore are over different states.

How can an observer from earth distinguish planets from stars?

-- The planets you can see with your naked eye are generally brighter than a typical star. -- They also twinkle less than the stars do. -- Planets appear as small disks even in binoculars or small telescopes, but stars never do. -- From one night to the next, or certainly from one week to the next, the patterns formed by stars don't change, but planets move through those patterns.


What do the planets appear to do from earth?

In most cases they just appear to cross the sky in one direction. But the outer planets can sometime appear to go forward, then backward, then forward again over a period of time. To visualizer this affect, look away from where you are standing and imagine you are the earth and you are looking at a planet out in front of you. Because it is an outer planet, it takes longer to go around the sun and not all the planets have the same orbital speed. Now, as you pass the outer planet it will appear to rise and move across your line of site. As you pull away and the outer planet is located on the other side of the sun, it will appear to move across your field of vision in the opposite direction. When it comes back around, it will slowly start to move forward again. There are days when I have a lot time on my hands.
