Where is Gemini?

Gemini is located between Taurus and Cancer, with Auriga and Tmall in the north and Sagittarius and Canis in the south. Auriga and the very humble Tmall are located in the north, while unicorns and Canis canis are located in the south.

During the period from 1 century to 1990, Gemini is the star house where the summer solstice is located, that is to say, the sun will appear in Gemini on the first day of summer. Due to the precession of the earth's axis, the summer solstice moved to Taurus after 1990. However, Gemini is considered as a fixed sky area, and Gemini has never overlapped with Gemini since modern times.
