Pretty simple question I think, but I am having trouble confirming a legitimate answer.

If things related to Mars are Martian, things related to Jupiter are Jovian, and things related to the Moon are Lunar, what do we call things related to the other major stellar bodies?

So far I have used Venusian for Venus, although I am unsure if this is incorrect, and there are a few names for things from Earth (Earthborn, Terran, etc...). I am just hesitant to follow simpler English naming conventions if there is already a more official term.

This is what I am thinking at the moment, but feel like it doesn't sound entirely right:

  • Sun - Solar
  • Mercury - Mercurian
  • Venus - Venusian
  • Moon (Luna) - Lunar
  • Mars - Martian
  • Jupitar - Jovian
  • Ganymede - Ganymean
  • Europa - Europan
  • Saturn - Saturnal
  • Titan - Titan (unsure if there is need for suffix)
  • Uranus - Uranian (Uranan?)
  • Neptune - Neptunal
  • Pluto - Plutonal (Plutan? Plutonian?)
  • Eris - Erissian

Please let me know if any of these are incorrect, or if there isn't an official naming convention.

  • $\begingroup$ Nice question ! Checked out on Wiktionary and almost all adjectives are ending with "-ian", like Neptunian, Plutonian, Uranian, Titanian, Saturnian, Ganymedian and indeed Venusian and Mercurian. The exception of course is Europa that will be European ! Found nothing about Eris . $\endgroup$

  • $\begingroup$ @DavidHammen That answers it perfectly. Apparently there are several names that can be used for each. Thank you very much. If you put it as an official answer I will choose that one. $\endgroup$ Commented Dec 12, 2018 at 15:53
