Uranus - the planet with the unfortunate-sounding name - has long been the butt of jokes.
But educators at a top science centre are trying to evade the constant innuendo with a more polite pronunciation.
Staff at Auckland's Stardome Observatory & Planetarium are teaching schoolchildren to call the seventh planet by its "less giggly" Latin version, ditching the traditional pronunciation.
Stardome's marketing manager Delyse Diack said children generally pronounced Uranus "in the way you expect", but educators pronounced the distant planet with an emphasis on the first syllable and the second syllable sounding "ra" rather than "ray".
Education manager Beth van der Loeff said around 240 children toured the planetarium every day and staff opted for the alternative Latin version "to make their lives easier".
