Which constellation is the closest to Earth?

Which constellation is positioned the closest to Earth (in regards to space)? Any additional information you can provide on the positioning or websites which detail this constellation will earn you 10 points.





Thank you very much.|||Constellations are not single objects - they are just the patterns that people see in the random positions of stars in the sky.





The closest star to our solar system is Proxima Centauri (part of the Alpha Centauri triple system) and that is located in the constellation Centaurus.





You can check out this page for information on Centaurus. But since the constellations are just patterns in the sky, some of the stars in that constellation are a lot farther away than some stars in other constellations.


http://en.wikipedia.org/wiki/Centaurus|||Constellations are not objects of space but only regions constituted of projections of stellar positions on the (imaginary) sky surface. Any constellation has many stars, all of which are at different distances from the Sun. The nearest star, however, is Proxima Centauri in the constellation of Centaurus, at 4.23 light years. Other stars in Centaurus, however, are much further. Beta Centauri is at about 350 light years form us.





A map of nearby stars is available at http://www.atlasoftheuniverse.com/12lys.… . Keep in mind that most of them are invisible to the naked eye. You can find more information by simply googling for "nearest stars".|||Constellations are arbitrary groupings of stars by their position on the imaginary celestial sphere. Each constellation consists of stars at many different distances, which overlap from constellation to constellation. I suppose you could say that Centaurus is the "closest" constellation because it contains the three stars which are closest to Sun, Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. The next nearest stars are Barnard's Star in Ophiuchus and Wolf 359 in Leo.|||Constellations are groups of stars in the same area of the sky. But in 3D, most of a single constellation's stars are at vastly different distances from Earth. It is just a line-of-sight coincidence that makes them into a group.


A few stars in Centaurus (Proxima and Alpha) are the closest ones to Earth. But I doubt few others in Centaurus are closer than many other stars in many other parts of the sky.|||The closest STARS to Earth are Proxima Centauri and Alpha Centauri a and b in the constellation of Centaurus in the southern hemisphere;s sky. Constellations have stars at variations distances from the the sun or Earth. No single constellation is closest to the Earth in regards to space, because the stars in any constellation are at various distances.|||Constellations are 2-dimension arrangements of stars on the celestial sphere. As such, there is no distance attached to them.





However, the constellation that contains the star closest to our Sun (and, therefore, to us) is called Centaurus.|||+The problem with your question is that constellations are made up of a number of different stars. The distances of these stars vary so it is really impossible to answer this question regarding how far a particular asterism is from earth|||Centaurus, perhaps. Constellations don't have an specific distance from earth, but the stars they contain do. More likely because they just form an object, and that doesn't mean they are together, some of the stars are far away then each other. Nice Day n n|||Constellations are not single objects. They appear to be 2d diagrams from our perspective. However, two stars right next to each other could be and probably are thousands of light years away from each other, and just as far from Earth.|||Constellations are not things, there patterns of stars in the sky. Because of that your question is impossible to answer.
