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.
Do the two meet for one final, fantastic explosion? Or maybe the sun just gets a bit of wind? Or maybe nothing of consequence happens at all? Only one way to find out.
Neptune is the eighth planet from the sun, the fourth largest, and a gas planet. It is named after the Roman god of the sea. Neptune is four times the size of Earth, and its day lasts a little more than16 hours. Its year is about 165 Earth years. Neptune's orbit is a perfect circle. The last stop on spacecraft Voyager's epic trip through the solar system was the gas giant Neptune.
