How far is Canis Major constellation from earth?

Answer 1

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.

Answer 2

Canis Major constellation is about 1,000 light-years away from Earth.
