Vesta - "The eternal Flame"
Vesta is about the inner flame - what we really "burn" for, in the meaning of purpose. She's about DEVOTION, commitment, sacrifice and service. It can also be about transforming sexual energy to a "higher calling" - or liberating the sexual energies within self.
Greek Mythology: Hestia is the firstborn child of Cronus and Rhea. She's as her later Roman counterpart the goddess of the eternal fire, the hearth. Poseidon and Apollo were fighting for her hand but she refused and stayed unmarried for all her life. In Greek tradition the "leading woman" in a household was responsible on getting the hearth fire burning. In Government buildings it was an Official and it was the first ritual to be hold, when a new city or village was developed.
Roman Mythology: Vesta the Goddess of hearth, home and family. She was a daughter of Saturn and Ops, therefore Sister of Jupiter, Neptune, Pluto , Juno and Ceres. Her Priestesses were called the "Vestal Virgins" and watched over the "eternal flame". Vesta didn't get involved with any of the stories of the other gods and goddesses. Cicero states it explicitly. The purity of the flames symbolized the vital force that is the root of the life of the community.
Some Astronomy: Vesta is the second-largest asteroid, both by mass and by volume, after the dwarf planet Ceres. It constitutes an estimated 9% of the mass of the asteroid belt. Vesta orbits the Sun between Mars and Jupiter, within the asteroid belt, with a period of 3.6 Earth years, specifically in the inner asteroid belt, interior to the Kirkwood gap at 2.50 AU. Its orbit is moderately inclined (i = 7.1°, compared to 7° for Mercury and 17° for Pluto) and moderately eccentric (e = 0.09, about the same as for Mars). Vesta's rotation is relatively fast for an asteroid (5.342 h) and prograde, with the north pole pointing in the direction of right ascension 20 h 32 min, declination +48° (in the constellation Cygnus) with an uncertainty of about 10°. This gives an axial tilt of 29°. (Ref. Wikipedia)
