How far awa is the constellation Sagittarius?
A "constellation" is better thought of as a direction away from the earth, not a physical object with a particular distance. Saggitarius's nearest star is Ross 154 at 10 light-years. It is too faint to be seen with the naked eye. Saggitarius is also the direction of the core of the Milky Way galaxy, about 27 thousand light-years distant.
