They can look similar in images, and some pits occur in impact settings, so shape alone cannot settle the difference. Look at formation clues, rim and ejecta, wall and floor visibility, and geologic setting together.
What is the difference between a lunar pit and a crater?
| Clue | Impact crater | Lunar pit |
|---|---|---|
| What the name describes | A feature formed by an asteroid, meteoroid, or comet striking the Moon and excavating material. The crater can be modified after the impact. | A steep-walled opening or depression; “pit” describes its shape, not a proven cause or cave connection. |
| Common visible clues | Often has a rim, a bowl-like or modified interior, and surrounding ejecta thrown out by the impact. Larger craters may be relatively wide and shallow. | May have steep walls, an overhang, or a dark opening where the floor is difficult to see. |
| What the clue establishes | A rim or ejecta can support an impact interpretation, but appearance and later modification matter. | A visible opening may suggest collapse or a void below, but an image alone may not establish how it formed or what lies beneath it. |
These are useful tendencies, not a strict either-or test. A pit can occur in an impact-related setting, and a feature’s lighting and scale can change how its walls and floor appear. NASA’s overview of lunar craters describes impact excavation and ejecta; NASA’s 2014 account of lunar pits describes their steep walls and the limits of interpreting images alone.
How do lunar pits form?
One proposed route is collapse: a roof over a subsurface void gives way, leaving a steep-sided opening. Some such openings may be skylights into former lava channels, but the label “pit” does not prove that origin. NASA planetary scientist David Kring describes skylights as holes broken into or punched through the roofs of subsurface channels of once-flowing lava, and calls pits related collapsed features in NASA’s Gravity Assist episode on lunar craters.
There is also an important complication: pit-like features occur in impact-cratering provinces where impact melt flowed. A pit in such a setting should not automatically be explained as volcanic or as a lava-tube entrance. NASA researcher Robert Wagner noted that images alone offered little evidence for the cause of an individual observed pit. The geological context and additional measurements matter.

Do Moon pits lead to caves?
Some may connect to subsurface spaces, but a dark opening or overhang in a photograph is not enough to confirm a cave. Radar evidence provides stronger support at one named site: in 2024, NASA reported that radar signals extended more than 200 feet from the base of the Mare Tranquillitatis pit. The full extent of the cave was unknown in that report. This finding supports a subsurface extension at that location; it does not establish that every lunar pit opens into a cave. See NASA’s report on the Mare Tranquillitatis pit.
What the measurements say—and what they do not
Size and count in NASA’s 2014 report
NASA’s 2014 account reported more than 200 pits, ranging from about 5 metres across to more than 900 metres in diameter. Its search covered only about 40% of the Moon under suitable lighting conditions at the time, so those figures describe a partial, historic inventory—not a complete census or a current 2026 count.

Temperature at Mare Tranquillitatis
NASA’s 2022 report found that shaded reaches within the studied Mare Tranquillitatis pit stayed around 63°F (about 17°C) in the reported observations and modelling. That result is specific to shaded areas of that pit; it is not a general temperature for lunar pits or caves. NASA explains the finding in its 2022 thermal study report.

- Look for impact evidence. A raised rim, bowl-like interior, and ejecta around a depression support an impact-crater interpretation, though later modification can alter these features.
- Check for an opening. Steep walls, a visible overhang, or a floor hidden in shadow are clues to a pit-like morphology, not proof of a cave.
- Consider the setting. A feature in a maria or an impact-melt area may have different plausible explanations. Setting informs interpretation but does not diagnose the cause by itself.
- Ask what data support a subsurface void. Images can show surface shape; radar evidence, as reported at Mare Tranquillitatis, can support an extension below the surface.
- Account for lighting and scale. Shadows can conceal floors or exaggerate apparent wall steepness, so avoid classifying a feature from one silhouette alone.
For a casual lunar viewing note, NASA planetary scientist David Kring says Tycho and its rays are visible with binoculars. That observation concerns a prominent crater and its rays; it is not evidence that binoculars resolve lunar pits.
