Transcript of Libra Constellation Project!

Libra "Scales" The Libra Constellation is best viewed in the Northern Hemisphere during the Spring Months. This constellation is ecliptic (by the equator) meaning for most observers, it is not circumpolar. The Libra constellation is the only constellation on the zodiac that is not a living thing. It Originally comprised the claws of the Scorpion, but was detached from Scorpius by the Romans to represent the vernal equinox. It has also been associated with the scales held by the goddess of justice. It was added by Julius Ceaser at the time of the establishment of the Julian calandar.
