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.
the star Yildun is 185 light years away from the sun!
4.2 light years away

Goldielocks is about 20 light years away which is about 70 years
ET is a gazillion light years away from Earth and scientists are unable to find the source of the flying shopping trolley
Mizar at 78 light years.
Megrez the Faintest of the Big Dipper Stars is 66 light years away.
5000 mile
The stars are unimaginably far away, well beyond any influence from Earth. Even then, they are far larger and more massive than Earth is.
The Big Dipper (and other constellations) are made up of stars that are difference distances from Earth. Every star that makes up the Dipper is a different distance. It only looks like the big dipper from where we are.
Since the Big Dipper (Ursa Major) is a north polar constellation, it appears to move very little, but it doesn't move, the Earth rotates on it's axis giving the appearance of motion. Actually, stars are so far away that, from Earth, you can't detect any motion.
The star, Alioth, in the big dipper (Which is the "tail" in the constellation Ursa Major) is approximately eighty light years from Earth.
Both of those constellations are actually just what we see. In actuality, those stars may be just as far apart from each other as they are from us, and are most likely hundreds/thousands of light-years away from each other. To sum it all up, all of those stars are different distances from the Earth.
Leo the Lion, is below the Big Dipper. In fact, ancient people used to think that the water from the Dipper, would spill onto the Lion and make him mad!
All stars twinkle in some way. This effect occurs because the stars are so far away from the earth that the light they emit actually bends a bit in Earth's atmosphere thus producing a wavering light. So yes, the stars of the little dipper do twinkle.
The little dipper is in our Milky Way Galaxy, actually not all that far from us. It is above the big dipper, so that it appears to be pouring into the big dipper. If you can see the north star, that is the tail (or end of the handle) of the little dipper. The middle stars of the little dipper are somewhat faint, but the two outside stars of the top and bottom of the little dipper pan are about as bright as the north star.
In a sense they are continually falling to Earth, but they are so far away that the curve of their fall is big enough to follow the circumference of the Earth.
