Moon phase today: What the Moon will look like on September 9
See the Moon phase expected for September 9, 2026 as well as when the next Full Moon is expected.
Tonight's Moon is nearing the New Moon phase, displaying only a faint sliver of light. According to NASA's Daily Moon Guide tracker, the Moon is currently in the Waning Crescent phase, with just 4% of its surface illuminated. The Grimaldi Basin is the sole notable feature visible tonight, best seen with a telescope or binoculars.
Full lunar cycles take roughly 29.5 days to complete, as the Moon orbits Earth. Our perception of the Moon's appearance is influenced by its position relative to the Sun, which determines the extent of its illuminated side visible from our planet. The Moon transitions through various phases during this cycle, from a narrow crescent to a half Moon, and finally to a Full Moon before commencing anew.
There are eight distinct moon phases: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter (or Last Quarter), and Waning Crescent. Each phase represents a unique stage in the Moon's journey around Earth and the gradual reveal or concealment of its illuminated side.
