In 'The Hitchhiker’s Guide to the Galaxy', the Vogons’ home planet is Vogsphere. The planet is associated with the Vogons’ harsh culture, bureaucratic institutions, and their rise to power within the Galactic administration.
Vogons are among the galaxy’s most unpleasant species: officious, bad-tempered, callous, and famously devoted to paperwork. They operate the Vogon Constructor Fleets, whose job includes demolishing planets to clear routes for hyperspace expressways. Their destruction of Earth is carried out for precisely that bureaucratic infrastructure project, leaving Arthur Dent and Ford Prefect searching for answers across the galaxy.
Vogsphere is also the source of several details in the series’ comic mythology. Vogons are described as having evolved from primitive creatures and surviving despite nature’s apparent lack of enthusiasm for them. Their poetry is notoriously terrible, ranking among the worst in the universe. Magrathea is a legendary planet of custom-built worlds, not the Vogons’ home, while Betelgeuse is associated with Ford Prefect and his background.
