Earth's Moon and the
planet Venus. Both the
Moon and Venus are bright enough to be seen during the day, and both are quite capable of showing a
crescent phase. To see Venus, which appears quite small, in a
crescent phase requires
binoculars or a telescope. In the
above dramatic daytime image taken from
Budapest,
Hungary, the
Moon and Venus shared a similar crescent phase a few minutes before the
Moon eclipsed the larger but more distant world. About an hour later, Venus reappeared.
