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 are planets seen in different locations at different times?

Because the planets are closer to us so when we look at the planets we can see them move so the closer an object is to you the easier it is to follow its motion. Hope you could use my answer


Why do the constellation appear to be in different part of the sky during different part of the year?

Because the earth is moving.


If a star in a constellation explodes what will happen to the constellation?

Depending on which constellation, somewhere between then next 20 and 2000 years people will see that star explode; the constellation will appear different for a year or five, and then disappear, leaving a whole in it.


What is Scorpius temperature?

The stars in a constellation like Scorpius appear to form a pattern, but are not a unit. A constellation consists of many stars spread out over a wide distance and of different temperatures. So there is no temperature that a constellation can be said to be.


Why doesn't the constellation Scorpio appear at the same time Orion appear?

Probably becasue it is in another part of the sky.There is a mythological significance to this, but since it's just a made up story, it has nothing to do with the actual reason why, which is that the two constellations are very nearly opposite each other in the sky.

How far away are the stars in Leo the constellation?

Any constellation is a group of stars that appear to form some kind of pattern, but have no connection with each other. They all happen to be in roughly the same direction from us, but they're all at different distances. So there's no such thing as a constellation's distance from us.

Why can't planets make a constellation?

The reason is because planets move too fast in relative comparison to other stars to be set in one constellation. After all, planet is Greek for "wandering star", meaning that it literally wanders amongst the constellations

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.


How does the appearances of a constellation seem to change at night?

The biggest notable change is that they appear to move across the sky. This is of course due to Earth's rotation, and not the constellation moving. Standing looking at a constellation, you will not notice it move. You would need something to relate it to, like something on the horizon. If you look very carefully, you will see movement. Over the course of a night, it will appear to move in an arc shape, rising and then setting. If you regularly viewed a constellation across a few days or weeks, you would also notice that the time they rise is different and the time they are visible at a certain point in the sky is different. You will not notice any change in the stars in relation to each other within a constellation. Even during a lifetime, never mind one night, a particular constellation will look the same to you, as the changes would be so slight. If the moon is visible near a constellation, you would notice some movement over the course of a night in relation to stars in the constellation, and certainly over the course of a few nights. If there is a planet near them, you will notice some movement, but not near as much as the moon. The nearer planets, like Venus and Mars are more noticeable in their changes compared to other planets.
