On Saturday evening (Sept. 27, 2014), about an hour after sunset, the thin crescent Moon will be just below the dwarf planet Ceres in Libra, with Saturn and the asteroid Vesta near by.
Libra is a constellation to which most skygazers rarely pay attention. Its brightest star, with the tongue-twisting name of Zubeneschamali, is barely third-magnitude, so it gets lost between the bright stars of Virgo to the WEST and Scorpius to the east. But this weekend Libra will shine.
Currently Libra is HOST to the planet Saturn and two of the largest and brightest asteroids, Ceres and Vesta. In addition, the crescent moon will be passing through on its monthly trip around the Earth.
Go out on Saturday night (Sept. 27) about an hour after sunset and look for the crescent moon, just three days REMOVED from the new phase. You should be able to see the portion of the moon that's not sunlit glowing with the ghostly light reflected from Earth, which is called earthshine or earthlight. Binoculars will help you see this.
