How many light years is cassiopeia away from earth?

Answer 1

A "distance" to Cassiopeia cannot be stated. Here's why. When we look out into space, we look at everything that is in that direction. We see "everything that's bright enough to be seen" with any view. If a small, modestly bright star is there and relatively close, we see it. (We wouldn't see it if it was far away.) If a star is really big and bright and really far away, we can see that, too. Considering the two example stars mentioned, if they are both "seen in a constellation" then the distance from one to the other is set aside. (We can't actually tell which is closer.) A constellation is a flat, 2-dimensional picture. Remember that it's a 3-dimensional universe, and the question cannot be approached in a 2-D way. Cassiopeia, a constellation in the northern hemisphere, is actually made up of several stars whose distance from here ranges from about 20 light years for one star (which is actually a binary star) to 441 light years for another, to 7800 light years for a third, to 11,650 light years for yet another. A link to the Wikipedia article (where some data for this article was mined) on this constellation is provided.

Answer 2

Approximately 11,000 light years. [See Link]

Answer 3

Delta Cassiopeiae or Ruchbah is approximately 99 light years from us.
