On Thursday, Oct. 29, the Moon is in the Waning Gibbous phase with 87% of its surface visible, according to NASA’s Daily Moon Guide. Observers can spot the Tycho and Copernicus craters without visual aids, while the next Full Moon is scheduled for Nov. 24.
What to see on the Moon this Thursday
The Moon is currently in its Waning Gibbous phase, Mashable reported. This means the lunar surface is 87% illuminated as of Oct. 29.
Observers do not need equipment to see the Mare Imbrium or the Tycho and Copernicus craters. Those using binoculars can identify the Grimaldi Basin, the Mare Humorum, and the Posidonius Crater.
Telescope users have access to more detailed sites, including the Caucasus Mountains, the Rupes Altai, and the Apollo 12 landing spot.
Pro Tip: Use a telescope to locate the Apollo 12 landing spot.
How the lunar cycle creates phases
The Moon takes about 29.5 days to orbit Earth. NASA explains that phases change based on the Moon’s position relative to the Sun and Earth, which alters how much of the illuminated surface is visible from the ground.
The cycle follows a repeating eight-phase sequence. It begins with the New Moon, where the Moon sits between Earth and the sun, rendering the side facing Earth dark and invisible.
As the cycle progresses, it moves through the Waxing Crescent, First Quarter, and Waxing Gibbous phases until the entire face is illuminated during the Full Moon. The cycle then reverses through the Waning Gibbous, Third Quarter, and Waning Crescent phases before returning to a New Moon.
Did you know? In the Northern Hemisphere, a Waxing Crescent shows a sliver of light on the right side, while a Waning Crescent shows light on the left.
Timing for the next Full Moon
Following the current Waning Gibbous phase, the lunar cycle will progress toward the next Full Moon. Reports indicate that this event will occur on Nov. 24.
Common questions about lunar visibility
Why can’t I see the Moon during a New Moon?
The Moon is positioned between Earth and the sun during this phase. This means the side facing Earth receives no sunlight, making it invisible to the naked eye.
What is the difference between waxing and waning?
Waxing refers to the period when the visible illuminated surface is increasing. Waning occurs when the illuminated portion begins to decrease, as is the case with the current Waning Gibbous phase.
How often does the full lunar cycle repeat?
According to NASA, the Moon completes its orbit and the corresponding sequence of phases approximately every 29.5 days.
