It is consistent, planets are from Roman or Greek, dwarf planets are roughly gods of creation regardless of mythology.
Other dwarf planets include Sedna (Inuit), Haumea (Hawaii), Makemake (Easter Islands), Gonggong (China), Orcus (Etruscan, but also Roman).
Though Pluto and Eris are intentional exceptions because they were thought to be planets for a long time.
Moreover, the extant names from the Roman pantheon are universal within the international scientific community. They are also nearly exhausted.
I find it tedious to reject names from other pantheons. Not least because they are exceptionally cool - Quaoar and ʻOumuamua are stellar and divine names. Of all things, should not astronomy inspire us to grok human culture as a global and syncretic whole, as opposed to a parochial set of divisions in which English speakers may only use Greco-Roman gods?
They could have named it Terminus, or Fontus, or Quirinus, or Vejovis, or... But whatever.
Anyways, the point I'm trying to make is that the space community is definitely thinking more globally nowadays and that it absolutely works. We went from no particular interest in astronomy amongst general population to meticulously following Perseverance's every step.
For example in Japanese, the visible planets have names that align with their own pre-Columbian traditions, e.g. Mars is named "Kasei" which means Firestar and Jupiter is named "Mokusei" which means Treestar. But when you get to planets discovered in modern times, Uranus, Neptune and demoted Pluto, they're respectively "Tennousei (Heavenly-King Star)", "Kaiousei (Sea-King Star)", and "Meiousei (Hades-King Star)", which are directly derived from the Western names given by their discoverers.
Now imagine the thousands of smaller named bodies in the Solar System, nobody's going to be bothered to come up with independent names for all of them for every culture, it would be too confusing. Imagine if everyone used native-tongue keywords in programming languages. Someone would send you a Python progam in French and it would be littered with sinon, sauf, Vrai, etc. While it might be convenient for the native speaker working alone, it would be a nightmare for interoperability.
Thus, newly discovered heavently bodies are referred to by the designations approved by the International Astronomical Union, in this case via its Working Group - Small Bodies Nomenclature.
When you think about it, would it actually matter?
The AST would be the same. As long as identifiers are defined for multiple locales it would be trivial to translate.
