Moon formation VFX?

Hello there. I’m new to VFX and simulations in general. I’ve been asked to create an “artsy” effect in Unity (URP VR) of the Moon formation, which i guess will rely a lot on particles and maybe some mesh pointcache.
Reference beeing :

I’m not after a scientifically accurate depiction ofc.
Could someone point me in the right direction ? How would you tackle this ? Simulation ? Hand made ?
I’ve been looking a bit into Blender FLIP Fluids, but i’m not sure if i should insist.
Thanks !
