How far is the constellation Perseus frm sun?
You can’t really say how far a constellation is. A constellation is just a group of stars, and even though the stars in a constellation look close together in the sky, in reality they might be very far from each other. Some of the stars could be relatively close to us, and some much farther away. Really, the only question you can answer is how far from the Sun each individual star in Perseus is. The first source lists a few of the brightest starts in Perseus, including how far away they are.
