It's the same with the stars in a constellation. From Earth, the stars appear to be close together, but they may be many light years apart.The stars in a constellation are phsically close to one another?
No, the stars in a constellation are millions or even billions of light years away from one another. They are even different distances away from the planet Earth.The stars in a constellation are phsically close to one another?Is that a question because you don't know, or are you just testing us?
And what do you mean "it's in the astronomy" - that doesn't make much sense.
Anyway, the stars in constellations have no relationship to each other, except that they are more or less in the same line of sight.

Nice try, Paul M, above, but the stars you see in the sky with the naked eye are not millions of light-years apart. They are from 10s to 100s of light years apart.
You should go look up how big a light year is and don't use millions so freely. The galaxies are millions of light years apart, not the local stars.
Sometimes, but usually not. Just in a similar line of sight.The stars in a constellation are phsically close to one another?No... not always. From our view on Earth, we can see two stars that look right next to each other, even though the true distance between them can be very far.The stars in a constellation are phsically close to one another?
No. The stars which comprise constellations are only close together in the night sky.
Their physical proximity to each other in space is not very close.
False.
A constellation is simply a pattern humans "see" in the arrangement of stars in the night sky.
Stars can be close or far from each other, they can be in the same area or separated by huge distances.
Being in a constellation doesn't require stars to be close together (or even associated).The stars in a constellation are phsically close to one another?
The key phrase in this question is "physically close." I am not sure what you mean by that phrase...10 light years, a Million Miles???
It is for certain that if the stars in a Constellation were physically close to one another you would not see two stars, you would see "One." For you to actually see "Two" with your naked eye, they have to be way - way - way apart.
We just see patterns in the arrangement of bright stars in the same general area as each other, and call that a
constellation. It is worthy to note that the ones we mark as
being in a constellation are always the brightest ones that can be seen easily with the naked eye... Nobody wants this to be really hard to see... (at least back in the old days)...
Several good answers already on this question, so I'll give you an example to illustrate.
In the "Big Dipper" (Ursa Major) the stars which form the side of the dipper away from the handle are Dubhe (top, multiple star) and Merak (bottom.) Merak is 79.455 light years from Earth. Dubhe is 123.78 light years from Earth. Based solely on that, it means the two are a minimum of 44.325 light years apart! That means approximately 265 *TRILLION* miles from each other! (Once you do the actual trigonometry, it will be somewhat different, but that gives you a close idea.)
