Libra, a constellation and the seventh sign of the zodiac. The sun formerly entered Libra in autumn, when days and nights balance each other in length. The name Libra, meaning The Balance, probably refers to this fact. Libra is bordered by Serpens Caput on the north, by Ophiuchus and Scorpius on the east, by Lupus and Hydra on the south, and by Virgo on the west. Its brightest star, with a magnitude of 2.61, is Beta Librae, or Zubeneschamali. Alpha Librae is a double star whose components have magnitudes of 2.76 and 5.15.
Venus is the second planet from the sun, and is about the same size as Earth. It is a terrestrial planet, meaning it has a solid surface. But the harsh conditions on Venus make it very inhospitable. Two spacecraft, Pioneer Venus 1 and Magellan, were able to penetrate the thick atmosphere of this planet.
