Earth has 7 quasi-moons, and scientists want you to nickname one

Naming Celestial Objects

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.

Examples of Dual Names

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 and  Their Orbits

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.

2004 GU9: Earth's  Quasi-Moon

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.

Public Naming Contest

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.

Zoozve: A Quasi-Moon Named by Accident

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.

Guidelines for Name Submissions

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.

Participation Open to All

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.

The Significance of Naming

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.
