Names by theme

Space and science names

Stars, constellations, orbital phenomena, elements and the people who worked them out.

Updated 27 July 2026

Star names are among the oldest continuously used words in any language — a great many arrived in English from Arabic, which is why so many begin with Al-. They tend to be short, unusual and easy to call, which is a rare combination.

The science half brings elements, phenomena and scientists, and it's where the catalogue's most quietly funny names live: naming a very fast animal after a unit of measurement never entirely stops being satisfying.

What's in this theme

  • Star names are unusually well suited to dogs — short, distinct, and almost never taken at the park.
  • Element and mineral names suit reptiles and fish, where grandeur costs nothing.
  • Luna and Nova are the two exceptions: both extremely common, and Nova collides with no.
