Going with Greek mythology and space, a god or I guess titan is known as Astraeus or if you would like it in Greek Ἀστραῖος. the name itself means starry but in legends, Astraeus is known as the god of stars, planets, astrology, and dusk. Astraeus is the father of the stars and the four seasonal winds, known as the Anemoi, through his marriage to Eos, the Dawn. The arrival of the winds is heralded by the rising of certain constellations. Astraeus is also associated with winds because winds often appear at dusk, and stars and planets begin to emerge at dusk. Astraeus's Roman name is Astraios. He is the father of all stars, including the fixed stars and the planets, or "wanderers". The planets are Phainon (Saturn, Phaethon (Jupiter, Pyroeis (Mars, Eosphoros/Hesperos (Venus, Stilbon (Mercury.

if you're not into that I suggest the name Lrya, it's a lyrical name for a celestial child, Lyra is the name of a small constellation first recorded by the ancient Greek astronomer Ptolemy

i think Sirius! In Greek and Roman mythology, Sirius is the god and personification of the star Sirius, the brightest star in the night sky, also known as the Dog Star, the most prominent star in the constellation Canis Major. the Greek version is Σειριος <3

So, not sure if I’m allowed to do this but I’m listing multiple names because I have far to many ideas,
1. estrela, Portuguese for star
2. Andromeda, a constellation and a character from a Greek myth
3. Astraeus, the Titian of the stars, plants, and the art of astronomy
4. Orion, A constellation and Greek hero
5. Polus, Latin word for the sky and heaven

I’d say Selene. Selene is the greek goddess and personification of the moon and after taking a look at your king I think the name totally fits !
Also, it’s pronounced (seh-LEH-neh) ^^

Some names:

Scourge (just for fun, fits the edgy look)

Katasterismoi - Greek for ‘placing the stars’, essentially what the Greeks called constellations.

(The) Pleiades - 7 stars, there is a cool Greek myth that these are the 7 daughters of the Titan Atlas that Zeus turned into stars

Achlys - Greek name that means ‘mist’ or the goddess of misery

Despoina or Despoena - Greek goddess of mystery (found two possible spellings of it idk)

The white from his piebald mut reminds me of ice, so I’m going to suggest Enceladus. This is the name of one of Saturn’s moon that is covered in white ice. It’s also the name a giant who was one of the offspring of Gaia and Uranus.
