The earth is rotating around the sun. Therefore the position of other stars (although millions of light years away) are in different orientation to that of the earth.
Constellations
You determine when fall begins by the date on the calendar. The fall equinox is when fall officially begins, although sometimes the weather can seem warmer or colder.
It doesn't mean anything. There are always stars next to the Moon. Actually the stars are much farther away, but the stars that happen to be in the same direction seem to be next to the Moon.It doesn't mean anything. There are always stars next to the Moon.

When you look at the stars at night, you can't really tell how distant they are. They can easily seem to be closer than they really are.
The celestial sphere.
As the Earth goes around the sun, it changes its position relative to the stars in those constellations. At times, some stars won't be visible as they will be behind the sun. This change in perspective isn't enough to make it appear as if they stars have taken a radically new position. They still seem to be just where they always have been. That's why the stars of each constellation stay in the shape of the constellation and instead it seems as though the whole constellation moves. Really, it's just us that are moving.
we have consterlations because they are jut made out of stars
Because their temperature seem to change too
Because their temperature is changing.
Stars are constantly moving, but their distance makes it unnoticeable for us. The reason we see different stars in different seasons is due to our position as we move around the sun each year. What that does mean is that at the same time each year, you will see the same stars in the same positions. During the night, as the Earth rotates, the stars seem to move across the sky. From night to night, because we orbit the sun, they appear to be in slightly different positions at the same time each night. Even then, you have to be looking carefully at the same time each night to notice. Because of that change, over the course of a few months they seem to have moved more considerably.

Both twinkle - even the sun does. However the relative size, as seen from Earth, means that the amount of "twinkle" is far more apparent for a star than for a planet. there is an apparent change in position of stars , so they seem to twinkle
Logically, no co-ordinates were specified with the changed position so it would seem that the changed position has not moved.
This is a simple one to answer. The Earth rotates and as it rotates, the stars seem to move across the sky.
It is because the Earth is orbiting the Sun. As our position changes, then the stars appear to be in different locations. It is like when you look at anything when you are moving. Something that is in front of you as you walk towards it, will be beside you when you get to it and behind you when you pass it. If you walk in a circle around something, which is what we are doing as we go around the sun, the things you see will seem to change position but will eventually come back to where they started when you complete your circle. So where stars appear to be at one time of year is where they will appear to be at the same time of year in another year.
Only if you look at it at the same time every night. If you look at it 4 minutes earlier each night, then it doesn't change position at all.
Stars actually do rotate.
