14. Mythology: In Greek mythology, Aries was a flying ram that saved the brother and sister Phrixus and Helle from being sacrificed to stave off famine (it was a setup by their stepmother, who hated the two). Helle fell off during the flight and drowned, but Phrixus made it to safety. Phrixus then sacrificed the ram to show his gratitude … to Zeus, rather than to the ram. The sacrificed ram’s fleece might also have been the golden fleece sought by Jason and the Argonauts.
15. Historical significance: Aries was once the constellation through which the sun passed at vernal equinox. While the vernal equinox has since moved into the constellation Pisces, it’s still sometimes called the “First Point of Aries.”
16. Symbolic significance: In ancient Greek culture, the horn (such as the one on a ram) was a symbol for fertility or renewal, which Aries once ushered in during the vernal equinox.

More Fascinating Facts About Aries
1. Aries includes a new, near neighbor. Aries includes Teegarden’s star, discovered in 2003 by a team led by astrophysicist Bonnard Teegarden. At a distance of about 12 light-years away, Teegarden’s star is one of the sun’s closest neighbors.
2. Three stars in one. The star in Aries known as Gamma Arietis, or Mesarthim, is actually three stars: a binary star system orbited by a third star, all about 204 light-years away. Gamma Arietis was one of the first double-star systems ever discovered, first identified as such by the English scientist Robert Hooke in 1664.
3. A ram to many. While past cultures might have had different names for other constellations, many agreed that Aries was the ram, including the Babylonians, Egyptians, Persians and Greeks.
4. Home to a planetary system. HD 20367, a star at the edge of Aries, is a class G dwarf star with an orbiting planet. Slightly larger than Jupiter, the planet completes a circuit around HD 20367 once every 500 days at an average distance of about 117 million miles or 187 million kilometers (a distance about 25 percent greater than Earth’s distance from the sun).
