Moon Phases Poster — Dark Edition II, Flat Illustration

This moon phases poster maps all nine steps of the 29.5-day synodic cycle — New Moon through Full Moon and back again — on a deep midnight navy field scattered with white star dots. Nine phases. One 3×3 grid. Zero clutter. Each phase is rendered in Kurzgesagt-flat bold illustration: hard edges, accurate shadow geometry, mid-century-meets-modern color blocking. Labels in caps serif keep it scientific. The result is wall art that works equally hard in a home observatory and a minimalist bedroom.

Frequently Asked Questions

How many moon phases are there?

Eight named phases make up the 29.5-day synodic cycle: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, and Waning Crescent. This poster shows all eight plus a closing New Moon — nine illustrations total — so the cycle reads as a complete loop.

What's the difference between waxing and waning?

Waxing means the illuminated portion of the lunar disk is growing — moving from New toward Full Moon. Waning means it's shrinking — moving from Full back toward New. The shadow geometry on each illustration reflects this accurately: waxing phases are lit on the right; waning phases on the left.

How long is a lunar cycle?

The synodic lunar month — measured from one New Moon to the next — is exactly 29.5 days. That's the cycle shown here. The synodic month differs slightly from the sidereal month (27.3 days) because Earth is simultaneously orbiting the Sun, requiring the Moon to travel a little further to return to the same phase.
