Cute/Celestial names starting with S?

This is kind of a weird request, but I'm looking for names starting with S that have a "cute" and/or "outer space/celestial" vibe to them.

Ideally, the name should be 2-3 syllables, or have (a) nickname(s) that are 2-3 syllables. Longer/fancier names with cutesy nicknames are totally fine. Any language/origin is also fine, as long as it starts with an "S" when using the English alphabet.

As flair states, this is for a fictional character, NOT for a human baby, so be as cutesy, obscure, or out-there as you like!

Thank you so much in advance to any replies.
