Unlocking the Moon’s Mysteries: A Beginner’s Guide to Locating Lunar Craters
The Moon, our celestial neighbor, has captivated humanity for centuries. For amateur stargazers, exploring the Moon is like opening a treasure chest of cosmic wonders. Among its many features, craters stand out as fascinating windows into the Moon’s history. If you’re new to stargazing, here’s your guide to locating and identifying craters on the Moon in a fun and straightforward way.
Why Are Lunar Craters Important?
Craters tell the story of our Moon’s tumultuous past. Formed by meteoroid impacts billions of years ago, these scars offer clues about the early solar system.

Some are massive and ancient, while others are smaller and relatively new. Learning their names and locations not only enriches your stargazing experience but also connects you to the broader narrative of cosmic exploration.
Getting Started with Lunar Craters
1. Choose the Right Time to Observe
The best time to observe lunar craters isn’t during a full Moon, as its bright light washes out surface details. Instead, aim for a crescent or gibbous phase. During these phases, the Sun’s light hits the Moon at an angle, casting shadows along its surface and highlighting the craters’ details.
2. Gear Up for Success
You don’t need expensive equipment to start. Here’s what you’ll need:
Binoculars: A pair of 7x50 or 10x50 binoculars is a great entry point for spotting larger craters.
Telescope: For more detailed views, a beginner telescope with at least 60mm aperture is ideal.
Moon Maps or Apps: Tools like Moon Globe or SkySafari can guide you in locating and identifying craters.
3. Learn the Moon’s Geography
The Moon is divided into two main regions:
Maria (Seas): These are the dark, smooth plains that are easy to spot. They serve as reference points for locating nearby craters.
Highlands: These lighter areas are rougher and more crater-filled.
Famous Craters and How to Find Them
1. Tycho (read blog 'Our Near Neighbours and visitors In Space....' by Roger)
Location: Near the southern pole of the Moon.
Appearance: One of the brightest and most distinctive craters, Tycho has a stunning ray system that extends across much of the Moon’s surface.
How to Spot: Look for a bright spot in the southern hemisphere. Its rays make it visible even through binoculars.
2. Copernicus
Location: Near the Moon’s equator, in the Oceanus Procellarum region.
Appearance: Known as the “Monarch of the Moon,” Copernicus is a large, round crater with terraced walls and a central peak.
How to Spot: Find it slightly north of the Moon’s center during the first or last quarter phases.
3. Clavius
Location: In the southern highlands.
Appearance: A large, ancient crater with smaller craters nestled inside it.
How to Spot: Look below Tycho. Clavius is especially striking in low-light conditions.
4. Plato
Location: At the Moon’s northern edge, near the Mare Imbrium.
Appearance: A dark, smooth crater, often called a “lunar lake.”
How to Spot: Look for a dark oval near the Moon’s northern edge. Its flat floor makes it stand out.
5. Mare Crisium
Location: On the Moon’s eastern side.
Appearance: A circular plain surrounded by craters. While not a crater itself, its boundary features small, distinct craters worth noting.
How to Spot: Easy to find during the waxing crescent phase.
Tips for Remembering Crater Names
1. Start Small: Focus on one or two craters per session to avoid feeling overwhelmed.
2. Use Mnemonics: Create associations for the names. For instance, 'My Very Educated Mother Just Served Us Nine Potatoes' i.e. order of planets away from the Sun....Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto (Pluto not actually classed as a planet but a 'dwarf' planet).
3. Draw or Sketch: Recreate the craters’ positions to reinforce their locations in your mind.
The Fun of Naming Craters
While official names are assigned by the International Astronomical Union (IAU), you can create personal nicknames for craters as you explore. These names can make your stargazing sessions more enjoyable and memorable, especially if you’re sharing the experience with family or friends.
Using Technology to Enhance Your Journey
Modern apps and websites make crater identification easier than ever:
Virtual Moon Atlas (Desktop): A comprehensive guide to lunar features.
Lunar Map HD (Mobile): A user-friendly app for locating craters.
A Lifetime of Discovery
The beauty of the Moon is that there’s always more to see. As you become familiar with its craters, you’ll uncover new details and deepen your connection to the night sky. Stargazing is a journey, not a destination, so take your time and savor each moment of discovery.
Whether you’re marveling at Tycho’s rays or tracing the smooth edges of Plato, remember that every crater you locate connects you to humanity’s shared wonder for the cosmos. So grab your binoculars or telescope, step outside, and let the Moon’s craters tell their ancient tales.
Happy stargazing!
