Moon in Waxing Gibbous phase on Oct. 20, 2026, says NASA

As of Tuesday, Oct. 20, 2026, the Moon is in its Waxing Gibbous phase with 65 percent of its surface illuminated, according to NASA’s Daily Moon Guide tracker. Stargazers preparing to observe this week’s lunar progression can spot major surface features including the Mare Crisium, Tycho Crater, and Mare Fecunditatis without visual aids, Mashable reported.

The Tech TL;DR:
• The Moon sits at 65 percent illumination on Oct. 20, 2026, in the Waxing Gibbous phase.
• Unassisted viewing tonight reveals the Mare Crisium and Tycho Crater, while binoculars expose the Endymion Crater and Apennine Mountains.
• An upcoming conjunction will place Saturn near the Moon during the night of Oct. 24–25 ahead of the Full Moon.

Tracking Lunar Illumination and Surface Features

The lunar cycle takes roughly 29.5 days to complete as the Moon orbits Earth, altering the visible fraction of its sunlit side from a slim crescent through quarter phases to a full illumination. For observers tracking tonight’s 65 percent waxing state, unassisted viewing conditions permit the identification of prominent lunar maria and impact structures. Observers utilizing binoculars gain visibility of the Endymion Crater, Alphonsus Crater, and the Apennine Mountains. High-magnification setups such as telescopes further resolve the Apollo 15 and 16 landing sites alongside Rima Hyginus, per NASA observations.

Moon and Saturn Align in South African Skies

South African stargazers can anticipate an additional celestial alignment later this week as the Moon appears close to Saturn in the night sky. The pairing will be visible during the night of 24–25 October, with both objects moving across the sky together, as reported by The South African. While the two bodies remain separated by vast distances—with Saturn positioned roughly 1.2 billion kilometers from Earth—their apparent proximity creates a conjunction visible without specialized equipment.

Saturn remains a prominent target throughout October following its opposition on October 4, 2026, an orbital alignment placing the planet opposite the Sun and maximizing its brightness and visibility duration. The subsequent lunar cycle culminates in the next Full Moon, scheduled for October 25 or 26 depending on the observer’s timezone. In South Africa, the Moon reaches its full phase at approximately 06:11 on Monday, 26 October, according to The South African.
