How much does the constellation Gemini weigh?

Constellations, including Gemini, do not have weight in the traditional sense, as they are not physical objects but rather patterns of stars as viewed from Earth. The stars in Gemini are at varying distances and masses, so any notion of weight would depend on the individual stars rather than the constellation itself. For example, the two brightest stars in Gemini, Castor and Pollux, have masses of about 2.0 and 1.0 times that of the Sun, respectively. However, the concept of "weight" is not applicable to entire constellations.
