Asteroid Names

I love asteroid names.

When you discover an asteroid, you get to propose a name. Names are formally approved by a working group of the International Astronomical Union. I joined that working group in 2018.

Rules govern what names can be used, though these rules have changed over time.

Many asteroids are named after noteworthy individuals, such as 5102 Benfranklin or 95962 Copito, an albino gorilla. Some are whimsical, such as 24680 Alleven and 13579 Allodd, or funny, like 88705 Potato. 6510 Tarry is a grateful tribute. 16232 Chijagerbs is a romantic gesture. Many are named after astronomers, including me!

I’ve had the privilege and pleasure of proposing asteroid names to honor extraordinary individuals. (I do not vote on names I submit.) These are the asteroids I have named, along with their citations:

Have you discovered a minor planet?

Are you proposing a name to the IAU?

I have created the following list of suggestions to help you select a name and craft a citation, based on my experience on the IAU Small Bodies Nomenclature Working Group.

These suggestions are intended to increase transparency of the naming process.  These are not rules, and discoverers are encouraged to first read the relevant naming rules. Each name and citation is evaluated individually by the working group. The working group may approve names that do not follow these suggestions. 

  1. Accuracy and Originality

    You are encouraged to spend time crafting a thoughtful, original citation. Some members of the Working Group do not look kindly upon citations that have been plagiarized from sources such as Wikipedia.

    As typos or grammatical errors in the citation can slow the approval process, it is good practice to have a citation reviewed by a second person before submission. (If you are a non-native English speaker, I would be happy to review your citation. You can contact me here.)

    It is your responsibility to ensure that the citation is factually accurate. For names proposed for individuals, this includes birth years and preferred pronouns.

  2. Clarity

    Citations are for a broad, worldwide audience. This includes non-scientists. Therefore, the working group encourages you to limit or avoid the use of acronyms.

    The citation should be easy to read and understand. Generally, a citation composed of two or three shorter sentences is more clear than one long sentence.  The citation should be written with complete sentences, not a series of bullet points.

    For names proposed for individuals, the citation is not intended to be a complete biography. 

    Names are considered for clarity and uniqueness. Although the working group evaluates names on a case-by-case basis, you may wish to propose a name that has a unique pronunciation. For example, if you wish to name an asteroid after "Jane Smyth" and there is already an asteroid "Smith", we would encourage you to submit the name "Janesmyth" instead of "Smyth," which can not be distinguished from "Smith" when said aloud. Although the IAU does not have pronounciation rules for names, common pronunciations are often considered by the Working Group.

  3. Cultural endorsement

    When submitting a name that derives from a culture not your own, we encourage you to work with members of that culture in both name selection and citation writing. If you have collaborated with a cultural group, the working group encourages you to describe that process in a separate email to the working group chair and vice-chair. This will speed up the name evaluation process.

  4. Avoid commercial ties

    A naming rule states,  “Names of a purely or principally commercial nature are not allowed.” The working group has, at times, interpreted this to include names of characters in popular movie and TV franchises.
