Researchers often give celestial objects two names: a formal designation for scientific precision and a more accessible nickname. This duality helps maintain clarity in exoplanet catalogs and black hole references while also creating a sense of connection.
Galaxy cluster "ACT-CL J0102-4915" is nicknamed "El Gordo," translating to "The Fat One" due to its mass. Similarly, "CEERS2_5429" is also known as "Maisie's Galaxy," named after the discoverer's daughter.
Quasi-moons are celestial objects that orbit the sun but remain close to Earth due to their synchronized orbits. Unlike Earth's Moon, their paths are influenced more by the sun’s gravity than by Earth's.
One such quasi-moon is 2004 GU9, also designated as asteroid 164207. This object is gravitationally influenced by both the sun and Earth but will eventually leave Earth's vicinity around the year 2600.
The International Astronomical Union (IAU) and the podcast Radiolab are inviting the public to suggest names for 2004 GU9. The contest aims to replace its formal designation with a more engaging name.
Radiolab host Latif Nasser previously named a quasi-moon of Venus "Zoozve" after a serendipitous discovery on a solar system poster. The IAU accepted this name due to the charming backstory.

The IAU prefers mythological names for celestial objects. While playful names like "Mooney McMoonface" are suggested, the final decision rests on adhering to the IAU’s standards.
The naming contest is open to everyone, regardless of age. Parents can submit names on behalf of their children, and participants are encouraged to suggest unique names that reflect their cultural heritage.
Naming a celestial object offers a sense of personal connection and contribution to astronomy. It’s a unique opportunity to leave a lasting legacy in the universe, much like Nasser's experience with Zoozve. For more details and to participate in the naming contest, visit the IAU's official guidelines and submit your name suggestion.
