What is the criteria one world to be called 'moon'?
The term "moon" typically refers to a natural satellite that orbits a planet. The criteria to be called a "moon" can vary, but generally, a celestial object must meet the following conditions to be considered a moon:
It must orbit a planet: The object must be in a stable orbit around a planet, rather than simply passing by it.
It must be natural: The object must be naturally occurring and not human-made.
It must not be a planet: The object must be smaller than a planet and must not be in a direct orbit around a star.
It must not be a dwarf planet: The object must not have cleared its orbit of debris and must not be considered a dwarf planet.
Therefore, an object can be called a moon if it orbits a planet, is natural, not a planet itself, and not a dwarf planet. However, there is no specific criteria for an object to be called the "one world moon" as this is not a commonly used scientific term
