How do planets, moons and stars get their names?
First of all, if we are going to draw inspiration for baby names from outer space, where do those objects in outer space get their names?
The naming of astronomical objects is decided by the International Astronomical Union. Reading up on how the IAU names planets and other astronomical objects is a great way to find inspiration and ideas!
For example dwarf planets in the Pluto system are named after figures from mythology, for example gods, goddesses and heroes.
When it comes to naming stars there is no rigid topic the IAU must follow. However guidelines suggest star names should be shorter, one-word names that are not too similar to existing names for stars, planets or moons.
Names that best represent the diverse living and ancestral cultural heritage from around the world are also favoured.
