The Sun enters the Zodiac sign Capricorn at December 22, 2020 and leaves it on January 20, 2021. Capricorn is the tenth astrological sign in the Zodiac, originating from the constellation of Capricornus. In astrology, Capricorn is considered an introvert sign, an earth sign, and one of the four cardinal signs. Capricorn is ruled by the planet Saturn. Individuals born when the Sun was in this sign are considered Capricorn individuals.
In Synastry, the natives of Capricorn are generally considered to be compatible with the natives of the other earth signs, Taurus and Virgo, and the natives of the water signs, Cancer, Scorpio and Pisces. Aries and Libra are signs of the other nature (masculine/extroverted), but are considered semi-compatible with Capricorn due to them having the same cardinal quality.
In mythology, Capricorn is sometimes depicted as a sea-goat, and sometimes as a terrestrial goat. The reasons for this are unknown, but the image of a sea-goat goes back at least to Babylonian times. Furthermore, the Sumerian god Enki's symbols included a goat and a fish, which later combined into a single beast, the goat Capricorn, recognized as the Zodiacal constellation Capricornus.
