Title: Astraea
Content:  Astraea, Astrea or Astria ("star-maiden" or "starry night"), in ancient Greek religion, is a daughter of Astraeus and Eos. She is the virgin goddess of justice, innocence, purity and precision. She is closely associated with the Greek goddess of justice, Dike (daughter of Zeus and Themis). She is not to be confused with Asteria, the goddess of the stars and the daughter of Coeus and Phoebe. The main belt asteroid 5 Astraea is named after her, and her name was also suggested for the planet Uranus.
Title: Astraeus
Content:  According to Hesiod's Theogony and Bibliotheca, Astraeus is a second-generation Titan, descended from Crius and Eurybia. However, Hyginus wrote that he was descended directly from Tartarus and Gaia and referred to him as one of the Gigantes. Appropriately, as god of the dusk, Astraeus married Eos, goddess of the dawn. Together as nightfall and daybreak they produced many children who are associated with what occurs in the sky during twilight. They had many sons, including the four Anemoi ("winds"): Boreas, Notus, Eurus, and Zephyrus, and the five Astra Planeta ("Wandering Stars", i.e. planets): Phainon (Saturn), Phaethon (Jupiter), Pyroeis (Mars), Eosphoros/Hesperos (Venus), and Stilbon (Mercury). A few sources mention one daughter, Astraea, the goddess of innocence and, sometimes, justice. He is also sometimes associated with Aeolus, the Keeper of the Winds, since winds often swell up around dusk.

Title: 5 Astraea
Content:  Astraea was the fifth asteroid discovered, on 8 December 1845, by Karl Ludwig Hencke and named for Astræa, a goddess of justice named after the stars. It was his first of two asteroid discoveries. The second was 6 Hebe. A German amateur astronomer and post office headmaster, Hencke was looking for 4 Vesta when he stumbled on Astraea. The King of Prussia awarded him an annual pension of 1,200 marks for the discovery. Hencke's symbol for Astraea is an inverted anchor, though given Astraea's role with justice and precision, it is perhaps a stylized set of scales, or a typographic substitute for one. This symbol is no longer used. The astrological symbol is U+2BD9 ⯙, a stylized percent sign. The modern astronomical symbol is a simple encircled 5 (⑤). After the discovery of Astraea, thousands of other asteroids would follow. Indeed, the discovery of Astraea proved to be the starting point for the eventual demotion of the four original asteroids (which were regarded as planets at the time) to their current status, as it became apparent that these four were only the largest of a whole new type of celestial body.

Title: Astraea
Content:  the political and astrological concerns. In Russia, Astraea was identified first with Elizabeth, then with Catherine the Great. The English epic poet Edmund Spenser further embellished this myth at the opening of Book V of The Faerie Queene (1596), where he claims that Astraea left behind "her groome | An yron man" called Talus. Shakespeare refers to Astraea in Titus Andronicus, and also in Henry VI, Part 1.
