How far away from Earth is the constellation Aquila?

I need this for a project and I can't find the answer anywhere! Some help would be greatly appreciated. And if you could list the website that you find it at, that would be fantastic because I need to cite all sources.|||You can't find the answer because there isn't one. Every star in Aquilla is roughly along the same line of sight from earth... out in the same general direction, but each star is at a different distance along that direction.





Examples of some star distances in Aquilla:





Altair 17 light years


Tarazed 463 light years


Epsilon Aquillae 154 light years


Althalimain 125 light years


Delta Aquillae 50 light years





And many many other random distances. The distance the other answerer gave was for another single star in this constellation, "Mu" or 渭 Aquillae.|||Aquila, just like any other constellation, is a collection of stars in the same general direction from us, but at vastly different distances. Altair, or Alpha Aquilae, is about 17 light years from the Earth. Nu Aquilae is the most distant star in Aquila visible to the naked eye, in reality over 100,000 times brighter than the Sun, but appearing faint because of its great distance, more than 10,000 light years.|||There is no answer.


All the constellations are just the patterns people see in the random arrangement of stars in the sky - the stars of a constellation are not related to each other and are at all different distances.





Each star in any constellation is unique.


So you could try this article:

Or this website:


http://www.nightskyinfo.com/constellatio鈥?/a>|||According to Wikisky.org Aquila is 33.898 parsecs away. It might be that this is measured from the presumed center of the galaxy to Earth? But there has to be a reasonable point of measurement. Sure it's a collection of stars, each with a different distance - but isn't a city a collection of buildings or its boundary a variable distance from any given point? Yet we seem to have no problem citing a distance in that case.|||there is no answer bcuz the stars are all at different distances.
