About this collection

Space has been inspiring human imagination since we first looked up, and the names of stars, planets, constellations, and missions translate beautifully to pets. They carry a sense of wonder and scale that everyday names rarely achieve, and they tend to age exceptionally well.

Celestial names are experiencing a sustained rise in pet naming. Luna (the moon) has been the most popular female cat name for several consecutive years. Nova suits any pet of sudden, dramatic energy. Stella is elegant and warm. Aurora suits white or iridescent-coated pets with a certain luminous quality. Sol suits golden or orange pets with warm, life-giving energy.

Planet names offer a full roster. Mars suits a red-haired or particularly assertive pet. Jupiter suits the largest pet in a multi-pet household. Saturn suits a pet with distinctive markings: rings of colour around their midsection or neck. Pluto, still beloved despite its demotion, suits an underdog (literally) or any pet who refuses to accept that their status has changed.

Star and constellation names go deeper. Orion suits a hunter: a cat who prowls with intent, or a dog with an exceptional nose. Sirius (the brightest star) suits the brightest, most outgoing pet in any room. Vega, Rigel, Altair, and Arcturus are names for pets whose owners appreciate having a name from an actual star catalogue.

Space mission names add another dimension: Apollo, Gemini, Voyager, Hubble, Cassini. Each carries a history of exploration and discovery. Artemis, now both the Greek goddess and NASA's lunar programme, is having a particular moment in both pet naming and space exploration simultaneously.
