Aquarians are compatible with a number of other signs, according to Chinese Astrology, but are most compatible with those born under the signs of Aries, Libra, Sagittarius and Gemini. The least compatible signs are considered to be Taurus and Scorpio.
Of course, there is no way to tell who is compatible with someone else, and star signs are only one way to look into potential matches. Aquarius signs do not tend to have typical relationships, and every partner is different. Other aspects of astrology can also impact the sign, like the position of the planets such as Venus and Mars or the moon. These planets/moon positions can influence a person's personality, according to Compatible-Astrology.
To understand compatibility for Aquarians, sun signs can be compared. This can give a general idea of who may get along well with the Aquarius, but this is just a quick way to compare and will have a number of factors that are not considered.
The Compatible-Astrology website claims that to understand how compatible a person is with another, calculations including planet placements from their dates of birth must be considered. The results must then be interpreted. Relationships also differ based on the partner being discussed, so gender may come into account when considering the Aquarius in question.
