Naming things in space is a mess. If you think you can just find a rock in the belt and name it after your cat or a favorite brand of soda, you’re in for a massive headache. There is a very specific, almost bureaucratic sentence for asteroid naming that governs exactly how these celestial bodies get their identities. Most people assume it’s a free-for-all, but the International Astronomical Union (IAU) basically acts like the DMV of the solar system.
Rocks are flying everywhere.
When a new object is spotted, it doesn't get a name immediately. It gets a provisional designation, which looks like a bunch of gibberish—something like 2023 RS1. It stays that way until the orbit is precisely determined. We're talking about multiple sightings over years. Once the math is solid, the discoverer gets a "sentence" or a short citation to propose a name. This isn't just a label; it’s a permanent record that lives in the Minor Planet Center's archives forever.
The Weird Rules Behind a Sentence for Asteroid
You can't just pick anything. Honestly, the restrictions are kind of wild when you look at them closely. The IAU has a set of guidelines that make naming a pet look like a breeze. First off, names have to be 16 characters or less. One word is preferred. It can't be offensive, obviously. But then it gets specific. You can't use a name that is primarily commercial. So, "Asteroid Coca-Cola" is never going to happen.

Pet names are discouraged.
Politicians and military figures? You have to wait. There is a mandatory 100-year waiting period after the person has died before their name can even be considered for an asteroid. This is to ensure that "historical perspective" is maintained. We don't want to name a giant space rock after someone who seems like a hero today but ends up being a villain in the history books twenty years from now. It’s a safeguard against the recency bias that plagues modern culture.
The sentence for asteroid naming—the actual citation—is where the magic happens. This is a brief paragraph that explains why this person or thing deserves to be immortalized in the stars. Dr. Gareth Williams, a long-time figure at the Minor Planet Center, has seen thousands of these. Some are poetic. Others are incredibly dry, listing academic achievements and dates of birth like a LinkedIn profile for the vacuum of space.
Why the Citation Matters More Than the Name
Think of the citation as the "why" behind the "who." When an astronomer submits a proposal, they aren't just sending a name. They are sending a justification. This justification becomes part of the official circulars published by the Working Group for Small Bodies Nomenclature (WGSBN).
If the citation is poorly written or contains factual errors, it gets kicked back. The IAU is notoriously picky about grammar and tone. They want these sentences to be dignified. You aren't just naming a rock; you are contributing to a catalog that will likely outlast the civilization that created it. It’s a weirdly heavy responsibility for something that usually involves a piece of debris sitting between Mars and Jupiter.
Common Misconceptions About Buying Names
Let's clear something up right now: you cannot buy an asteroid name.
There are plenty of websites out there—you've probably seen the ads—that claim they will let you "name a star" or "buy an asteroid" for fifty bucks. It’s a scam. Or, at the very least, it's a "novelty gift" with zero scientific standing. These companies have no authority. The only way to get a name officially recognized by NASA, the ESA, and every observatory on Earth is through the IAU process. If someone sold you a certificate for an asteroid named "Best Mom Ever," the scientific community still calls it (12345) 1998 XX.
The process is slow. It can take decades from the moment of discovery to the moment the name is officially minted. Take the case of 4147 Lennon, 4148 McCartney, 4149 Harrison, and 4150 Starr. These weren't named until 1990, long after the Beatles had changed the world. The discoverers have to be patient, and the citations have to be perfect.
Crafting the Perfect Asteroid Citation
When writing that crucial sentence for asteroid recognition, brevity is king. You have to pack a lifetime of achievement or a significant cultural impact into a few lines. For example, look at the citation for Asteroid 27431, named "Jimcoleman." It honors a specific educator. The sentence mentions his years of service, his impact on students, and his dedication to science. It’s simple, effective, and follows the rules.
- No commercialism: You can't mention a company.
- No "shouting": Don't use all caps or excessive exclamation points.
- Fact-check everything: Dates must be exact.
- Third-person only: It’s a formal record, not a diary entry.
Sometimes, the names get a bit nerdy. There are asteroids named after characters in The Lord of the Rings, like 1604 Tombaugh (okay, that’s a person, but 26027 Cottrill or various Hobbit-themed names exist). There are rocks named after Frank Zappa and Malala Yousafzai. The diversity is actually pretty cool once you get past the rigid rules.
The Evolution of the WGSBN
The WGSBN is the group that actually hits the "approve" button. They meet regularly (virtually and in person) to go through piles of naming proposals. In the past, this was a much more closed-off process. Today, it’s slightly more transparent, but the gatekeeping remains for a good reason. With the advent of automated sky surveys like Pan-STARRS and the Vera C. Rubin Observatory, we are finding thousands of asteroids every month.
If we let everyone name every pebble they found, we’d run out of names or end up with "Asteroid McAsteroidFace" in the official records.
The WGSBN ensures that the "sentence for asteroid" honors remain prestigious. They limit the number of proposals a discoverer can submit in a given period. This prevents one massive survey team from hogging all the names and filling the sky with their friends and family members. It keeps the celestial landscape balanced.
How to Actually Get Involved
So, you want to name one? You basically have two paths. You can become an amateur astronomer, buy a high-end CCD camera and a telescope, and spend years hunting for undiscovered objects in the main belt. Or, you can do something so significant on Earth that a discoverer notices you and decides to write a citation in your honor.
The latter is actually more common than you'd think. Many asteroids are named after teachers, local community heroes, or scientists who have contributed to the field in ways that don't involve telescope time.
If you are a discoverer, you should start drafting your sentence for asteroid proposal early. Look at previous examples in the MPC circulars. Mimic the tone. Be precise. Avoid flowery language that doesn't add value. The committee hates fluff. They want to know exactly who the person is and why they matter to the world.
Practical Steps for Naming and Citations
If you find yourself in the rare position of naming a minor planet, follow these steps to ensure the IAU doesn't toss your proposal in the trash:
- Verify the Number: You cannot name an asteroid until it has been assigned a permanent number. This happens after the orbit is confirmed by several "oppositions" (basically, seeing it at different points in its orbit over several years).
- Check for Duplicates: The name cannot be similar to one that already exists. "Wisdom" and "Wizdom" would be a conflict.
- Draft the Citation: Write your sentence clearly. Focus on the individual's specific contributions to their field or society.
- Submit through the Portal: Use the WGSBN's official submission system. Don't email them directly; they won't answer.
- Wait: The review process can take months. Be patient.
Naming a piece of the solar system is one of the few ways to achieve a type of literal immortality. Long after the Earth is gone, that rock—and the sentence attached to it—will still be looping around the Sun. It’s a small bit of human history etched into the mechanics of the universe.
To stay updated on newly named asteroids, regularly check the WGSBN Bulletin. This publication lists every new name approved by the IAU along with the official citation. It’s a fascinating read that highlights the diverse range of people and places that now have a permanent home in the stars. If you’re serious about the science, start tracking the Minor Planet Center’s daily updates to see which objects are nearing their "numbering" phase, which is the prerequisite for any naming proposal.
