The Moon reached Third Quarter phase on 2026-10-03, with 53% of its surface visible from Earth, according to NASA's Daily Moon Guide tracker.[^1]

For observers on this date, telescopes will resolve the Apollo 13 landing site and Schiller Crater.[^6]

The next full Moon will occur on 25 or 26 October 2026, depending on the observer's timezone.[^3] The full lunar phase cycle runs approximately 29.5 days, divided into eight distinct phases.[^5]

Guidance published this week advises beginner skywatchers to track one complete lunar cycle to learn the Moon's predictable pattern of waxing and waning.[^2] Binoculars are recommended for initial lunar, star cluster and Milky Way viewing before purchasing a telescope.[^4]
