June 6 constellation

The sixth is Gemini.

Gemini refers to the date of birth from May +0, 265438 to June +0, 265438. It is the third house of the zodiac, located in the east of Taurus and the west of Cancer. Represents impetuousness and communication.

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.

Extended data:

In 270 BC, the Greek poet Aratus wrote Things, in which 47 constellations were mentioned. According to the star regions recorded in Celestial Bodies, due to precession, the Antarctic in the period described in the book is not consistent with the current Antarctic, so it can be inferred that the starry sky recorded in the book is before 2000 BC;

At the same time, the blank area of the starry sky record indicates that the observer should be near 35 to 36 north latitude. So some people think that the practice of dividing the starry sky into constellations originated from Babylon and Sumer in Mesopotamia, and the constellations of Greece and Egypt may have been introduced from this area.

In the second century, Ptolemy recorded 1022 stars in 48 constellations in his astronomical masterpiece, which is also the embryonic form of modern constellations. After that, many astronomers filled the Ptolemaic constellation with new constellations. Valle in 1603, Jahannes Hewelius in 1690, and Llakaj in 1752 have named the constellations in Nantian in two centuries.
