Juno, in Roman religion and mythology

Juno, in Roman religion and mythology, wife and sister of Jupiter. In early Roman times she, like the Greek Hera (with whom she was later identified), was goddess and protector of women, concerned especially with their sexual life. In later religion she became, however, the great goddess of the state and was worshiped, in conjunction with Jupiter and Minerva, at the temple on the Capitol.

In Roman religion, the chief goddess and female counterpart of Jupiter. She was identified with the Greek goddess Hera. With Jupiter and Minerva she was a member of the Capitoline triad of deities traditionally introduced into Rome by the Etruscans. She was connected with all aspects of the lives of women, particularly marriage. Individualized, she became a female guardian spirit; as every man had his genius, so every woman had her juno. Her temple in Rome eventually housed the Roman mint, and she was invoked as the savior of the state. Her sacred bird was the peacock.

Juno

(asteroid no. 3), an asteroid discovered in 1804 by the German astronomer K. Harding. Juno was the third asteroid to be discovered. Its mean distance from the sun is 2.67 astronomical units. Its orbit is inclined 13.0° to the ecliptic and has an eccentricity of 0.256. Its brightness at mean opposition is 8.7 stellar magnitudes. Juno, which has a diameter of about 225 km, is one of the four brightest and largest asteroids. It is among the ten asteroids the positional observations of which are made as carefully as possible in order to determine the position of the vernal equinox, which acts as the reference point for right ascensions, as well as to determine the position of the equator of star catalogs.
