Our three nearest neighbours in the solar system grace the western sky at nightfall, February 21, 2015. At upper left, the moon's overexposed sunlit crescent is topped by the Earthlit sun-shadowed portion. At lower centre, Venus appears just to the left of fainter Mars. Completing a nearly equilateral triangle at upper right is the star Algenib, nearly 400 light years distant in the constellation Pegasus.
