How many light years away is the constellation cancer?

i've tried to google this.

if you know a good website will you give me the link please?

but if you know the answer that is good too (:

10 points for best answerHow many light years away is the constellation cancer?It's a group of stars which are distant from each other and just appear to make a pattern from here. Tegmine, the brightest "star", is a binary 78 light years away, and Beta and Iota Cancris, Asellus Borealis and Australis and Acubens are all roughly 200 light years away, so although there isn't a definite answer there is, unusually for a constellation, an approximate one.How many light years away is the constellation cancer?
Constellations are just imaginary connections between the points of light made by the stars. That is, the stars of a constellation are at widely varying distances from the human observer. Each star will have a different distance.How many light years away is the constellation cancer?cancer, like all constellations, has no physical manifestation. it is just a pattern of stars as seen from earth. the stars are all at different distances.How many light years away is the constellation cancer?
I agree with the other posts - there is no exact answer because a constellation is a random collection of stars.



However, it is interesting that EVERY star we see is withing the Milky way galaxy, our galaxy. That means that evey star in Cancer is within 100,000 light years - the width of the galaxy.



But you can do even better. The stars we see are actually within the small region of the galaxy that is close to our sun. So every star we see with the naked eye is probably within 500 light years.



If you look up the distance to the major stars in Cancer, you can pin it down to a specific range.How many light years away is the constellation cancer?"Constellation" is a human invention. It's just an arbitrary group of stars that vaguely resembles some mythical person or creature. In reality, most of the stars in a given constellation have little or no connection to each other and their spatial distances can vary by *thousands* of light years. Sorry, but there's no real answer to your question.
