Aries（LatinAries，Astronomical symbols♈），ZodiacOne, with an area of 441 square degrees, accounting for 1.1% of the total area of the day, ranking 39th among 88 constellations of the day[9]Aries is a weak constellation. There are only two bright stars brighter than the third class and only four bright stars brighter than the fourth class,Brightest starbyLou Susan(Alpha Aries).Aries inancient GreekWell known because at that timeVernal equinoxIt's in Aries.becauseprecession of the equinoxesThe vernal equinox has moved toPisces。
Between the first century and 1990,Aries PalaceIt's the vernal equinoxStar PalaceOn the first day of spring, the sun will appear in Aries.At the same time, since astronomers use the vernal equinox as the origin of the right ascension when establishing the equatorial coordinate system, the vernal equinox is represented by the symbol of Aries Palace.becausePrecession of earth axisAfter 1990, the vernal equinox moved toPisces Palace。However, Aries is a fixed sky area artificially defined, and since modern times, Aries does not coincide with Aries.

Aries was originally considered as a constellation related to sheep. It came from 1350 BC to 1000 BCBoundary stone。On these boundary stones, the image of the ram on the zodiac is quite different from that of other characters.But these stars may not coincide with modern Aries.[5]
