The constellation Gemini is not a single star but a group of stars, with its two brightest stars, Castor and Pollux, located approximately 51 light years and 34 light years away from Earth, respectively. The distance to other stars in the constellation varies, with some being much farther away. Therefore, the distances can differ significantly depending on which star in Gemini you are referencing.
350,876,543,010 light years away
The stars in any constellation all tend to be different distances from us. They just appear as a pattern as we look at them. Of the stars in Gemini, the nearest is 33.7 lightyears away. That is about 318,826,616,925,973 kilometres or 198,109,675,076,288 miles away.
Pollux is 35 Light-Years away from Earth. (I got my info from my earth science book from school.)
Gemini is a temporary alignment of stars and open clusters with different distances. The closest star is GJ 251, at 18.2 light years. The open clusters are M35 aka. NGC2168 at about 2800 light years (?), NGC2158 at about 11700 light years, and the "Clown Face" or Eskimo nebula at 2900 light years.
49,666,845 light years away from earth
The Gemini constellation itself does not have a specific distance since it is composed of multiple stars located at varying distances from Earth. For example, the two brightest stars in Gemini, Castor and Pollux, are approximately 51 and 34 light-years away, respectively. The constellation is visible in the night sky and serves as a reference point, but its stars are not all at a uniform distance from us.
Phrekad is approximately 48.6 light-years away from Earth.
The distance to a star located 100 light years away from Earth is 100 light years.
Arcturus is approximately 37 light years away from Earth.
Betelgeuse is approximately 600 light years from Earth.
The polaris is 430 light years from Earth.
