Moon phase for October 6, 2026: Waning Crescent at 21% visibility

The Moon is in the Waning Crescent phase on Tuesday, October 6, 2026, with 21% of its surface visible, according to NASA's Daily Moon Guide tracker. Visibility is decreasing nightly as the lunar cycle approaches the New Moon. The next Full Moon is expected on October 25 or 26, depending on timezone. Skywatchers can still spot the Aristarchus Plateau and Kepler Crater without aids, while binoculars or telescopes reveal the Grimaldi Basin and Gassendi Crater. Moon phases occur because the Moon orbits Earth in roughly 29.5 days, changing its position relative to Earth and the Sun. The eight phases range from New Moon to Full Moon and back, with the current Waning Crescent being the final stage before darkness.
