Do stars of a constellation have any physical relation?

Some of the brighter constellations contain stars that are part of the same "moving group", that is, stars that were formed from the same nebula but are no longer bound together as a star cluster. They can be identified as a group from their similar motion and age. Parts of Ursa Major, Orion, and Perseus, among others, consist of related stars. Other stars in these constellations are just coincidentally located in the same direction from us and are at greatly different distances.Do stars of a constellation have any physical relation?No. Most of them are actually really far away from each other. They only create a pattern because of how we view them from our position. If we could look at them from another angle, it would be a completely different picture.Do stars of a constellation have any physical relation?No they don't. Constellations were named by their apparent shapes as observed by humans, that's the only relation. Moreover, the shapes isn't even fixed.Do stars of a constellation have any physical relation?Well- it depends....generally we look to the sky and see the "big dipper" (ursa major) but our view is shaded at best....some of our known constellations are a view of "just from Earth".....we might see all the stars of say Scorpio and the Snake, and they might appear all as bright as each other, in fact seem related, but in reality are 1000's of LY away from each other, regardless of our perseption of them hope this helpsDo stars of a constellation have any physical relation?
NO



in nearly all constellations, people just drew lines between stars that were bright, and nearby in the observable sky. In most cases however, stars of similar brightness, as observed from Earth, are a mix of very bright but very distant stars, and much less bright but much closer stars.



So the distance between two stars of a given constellation can be hundreds of light years - which means that, for all practical purposes, the interaction will be so weak as to be indetectable.
