There is no single official lunar crater named “New Moon.” In astronomy, new Moon is a phase (Sun–Moon–Earth geometry), not a map label on the surface. Official names for craters and other features on the Moon are approved by the International Astronomical Union (IAU) and listed in the Gazetteer of Planetary Nomenclature (maintained with USGS). Most large craters honor deceased scientists, explorers, and scholars—not Moon phases. If you are searching because you heard a “new crater” headline, look up the exact name in the Gazetteer; new approvals are announced there and in IAU/USGS news posts (for example, crater Brill was approved in 2023).

How Lunar Craters Get Their Names — and Why It Matters
The International Astronomical Union (IAU) governs all official lunar crater nomenclature through a formal approval process that has been in place since 1919. Craters on the Moon are named almost exclusively after deceased scientists, artists, explorers, and scholars who have made significant contributions to human knowledge — a tradition that transforms the lunar surface into a kind of celestial hall of fame. The IAU's Gazetteer of Planetary Nomenclature is the authoritative database where all approved names are catalogued and publicly searchable.
This system wasn't always so orderly. Early lunar cartographers like Giovanni Battista Riccioli, who published his influential Almagestum Novum in 1651, established many of the naming conventions still in use today. Riccioli named prominent craters after figures like Tycho Brahe, Copernicus, and Kepler — names that remain on modern lunar maps. He also introduced the poetic tradition of naming large dark plains maria (seas), giving us the Sea of Tranquility (Mare Tranquillitatis) and the Sea of Serenity (Mare Serenitatis), regions steeped in the same atmospheric gravity that draws people to the new moon each month.
Key facts about the lunar naming system:
- The Gazetteer includes thousands of named lunar features; counts grow as names are approved. (Many listings are lettered satellite features—e.g., Tycho A, Tycho B—around larger named craters.)
- Craters are usually named for deceased people who contributed to science, exploration, or related fields, per IAU rules for the Moon.
- Proposals go through the IAU Working Group for Planetary System Nomenclature (WGPSN).
- Do not trust social posts that claim a crater was named after a living celebrity or sold to the public—that is not how IAU naming works.

Real crater names you can pair with “new Moon” symbolism (fact-checked)
Important correction: There are no IAU-approved lunar craters named Selene, Luna, or Hecate. Those words evoke Moon mythology, but they are not official crater names on the Moon. The large crater Hecataeus sounds similar but is named for the ancient Greek historian Hecataeus of Miletus, not the goddess Hekate.
For spiritual practice, you can still anchor a new Moon ritual to real named craters—the stories belong to the people the IAU honored, which is its own kind of depth.
- Tycho — Spectacular ray system; often easiest to see around full Moon, but the name honors Tycho Brahe and his era of careful observation.
- Kepler — Honors Johannes Kepler; a natural reminder of motion, cycles, and mathematics under a dark Moon sky.
- Copernicus — Honors Nicolaus Copernicus; a symbol of paradigm shift—useful when you are resetting assumptions at a new Moon.
- Plato — A walled plain named for the philosopher Plato; a prompt to look beyond appearances, similar to how a new Moon is “invisible but present.”
- Endymion — Named for the mythological figure from Greek lore (an allowed style for some lunar feature types); if you want myth on the map, verify the feature type and spelling in the Gazetteer rather than assuming.
Always confirm any name at planetarynames.wr.usgs.gov before building teaching or ritual around it.

What the New Moon Phase Reveals About How We Name the Cosmos
The new moon has functioned across cultures as a symbol of beginning, concealment, and sacred potential — and this symbolism is encoded not just in astrology, but in the very act of naming celestial features. In ancient Babylon, the new moon (noumenia in Greek) marked the start of the calendar month and was a moment of civic and religious renewal. The Greek philosopher Plutarch wrote extensively about the Moon's phases in De Facie in Orbe Lunae, linking the dark moon to the soul's journey between incarnations.
This cultural depth explains why the act of naming lunar craters carries such weight. When the IAU names a crater after Marie Curie (the crater Curie, located on the far side) or after the poet Omar Khayyam, it is performing a version of the same ritual that ancient cultures enacted at each new moon: marking the invisible, honoring the unseen, and consecrating what is yet to come. The far side of the Moon — permanently hidden from Earth — is particularly rich with this symbolism, home to craters named after figures who worked largely outside mainstream recognition in their own time.
For those who track lunar cycles intentionally, this connection between nomenclature and new moon energy offers a meaningful practice:
1. Identify the zodiac sign of the upcoming new moon 2. Research craters named after figures associated with that sign's themes (e.g., scientists for Aquarius, artists for Libra, philosophers for Sagittarius) 3. Use that figure's work or biography as a meditation anchor during the new moon window 4. Set your intentions informed by both the cosmic placement and the human story behind the name
This is the kind of layered, cross-disciplinary ritual that the Lunar Guide personalized lunar calendar is designed to support — connecting astronomical precision with meaningful personal practice.

How to Find and Track Lunar Crater Names for Personal Practice
The most reliable source for lunar crater names is the IAU's freely accessible Gazetteer of Planetary Nomenclature at planetarynames.wr.usgs.gov, which allows you to search by name, coordinates, or the person after whom a feature is named. Alongside this, NASA's Moon Trek platform offers an interactive topographic map where you can visually locate and explore named craters in extraordinary detail.
For those integrating lunar tracking with wellness or spiritual practice, here's a practical approach:
- Before each new moon, identify the sign and key themes (transformation, communication, ambition, etc.)
- Search the IAU Gazetteer for craters whose namesakes embody those themes
- Use Lunar Guide's daily insights to align your journaling or reflection with the specific lunar moment
- Record your intentions using voice journaling — Lunar Guide's voice journaling feature is particularly useful here, allowing you to capture the intuitive, unedited thoughts that the new moon tends to surface
- Revisit at the full moon to assess how those intentions have developed, using the crater's namesake as a symbolic mirror
A common misconception worth addressing: many people assume that craters are visible only during the full moon, when the surface is fully illuminated. In fact, craters are most dramatically visible during the crescent and quarter phases, when low-angle sunlight casts long shadows that define their rims. This is a useful metaphor — the new moon's darkness is not an absence of detail, but a different kind of revelation.
