Night Sky Tonight December 17, 2025: Moon Phase, Planets, Meteor Showers and Today’s Space News
A thin waning crescent Moon leaves skies dark tonight, with just 6% illumination and moonset early in the evening. Jupiter is prominent, Saturn remains visible after sunset, and the Geminid meteor shower fades as the Ursids begin to rise. The Moon reaches apogee at 6 UTC, its farthest point from Earth this month. New moon arrives late December 19 in U.S. time zones.
