Tomorrow night's first quarter moon appears in the zodiacal constellation Virgo, close to the right star Spica. Spica is one of the brightest stars of late spring and early summer. Use the moon to much valued celestial object. Spica is so large compared to our sun and voluminous too. The star is really two stars, one seven times bigger than our sun and the other is four times.
Their brilliance, hard to imagine, is 12,000 times brighter than our sun. The star is 250 light years away, one of the farthest bright stars in our sky.
