Moon phase today: What the moon will look like on October 10
The Moon is up and easy to spot tonight. Its surface is covered in craters and plains that are nice and easy to see, thanks to where we are in the lunar cycle. The lunar cycle is the Moon’s regular orbit around Earth, which causes it to go through different phases from new to full and back again.
What is today’s moon phase?
As of Thursday, Oct. 10, the moon phase is Waning Gibbous. Tonight, only 84% will be lit up, according to NASA's Daily Moon Observation.
The moon is covered in interesting craters, mountains, and Apollo landing spots. And we can see lots of them tonight. With just your naked eye, spot the Oceanus Procellarum, the Mare Serenitatis, and the Mare Tranquillitatis. If you have binoculars, pull them out to see the Grimaldi Basin, the Mare Humorum, and the Gassendi Crater. And if you have a telescope, you'll also see the Rupes Altai, Fra Mauro Highlands, and the Rima Hyginus.

What are moon phases?
NASA explains that as the Moon completes its 29.5-day orbit around Earth, it passes through a series of phases. These changes happen because the positions of the Sun, Earth, and Moon relative to each other shift over time. From Earth, we see the Moon as fully bright, partially lit, or completely dark, but the same side always faces us. The differences in appearance come from how much sunlight hits its surface at each point in its orbit.
The eight main moon phases are:
New Moon - The moon is between Earth and the sun, so the side we see is dark (in other words, it's invisible to the eye).
Waxing Crescent - A small sliver of light appears on the right side (Northern Hemisphere).
First Quarter - Half of the moon is lit on the right side. It looks like a half-moon.
Waxing Gibbous - More than half is lit up, but it’s not quite full yet.
Full Moon - The whole face of the moon is illuminated and fully visible.
Waning Gibbous - The moon starts losing light on the right side. (Northern Hemisphere)
Last Quarter (or Third Quarter) - Another half-moon, but now the left side is lit.
Waning Crescent - A thin sliver of light remains on the left side before going dark again.
