Tight specifications, but input would be appreciated..

I'm seeing what's available in a fairly simple space, or possibly science-themed name for my third born. 

My first two are:
Fin Diego &
Ché Montreo (both boys)

Some names we're considering for the first (sex unknown):
Sol
Mars
Moon (we wouldn't really use this - I think it would confuse the heck out of my children. I like the atmosphere of it though, although that could be associated from the pure sophistication of the famous Howard Moon)

And that's all I've really found/thought of in the astro theme first-name-wise. I definitely want to stick to one syllable, but obvious names like Star and Skye are out (I have a neice called Skye anyways). Scientist names, like Neil perhaps - while that one's actually pretty kickass.. just not pretty enough. :P

The middle name is going to be Cielo (see-AY-loh I think) which is the Spanish word for heaven (I'm an atheist. but close enough!) AND it's another three-syllable name that rhymes with Diego and Montreo (there's seriously like, three options that fit the requirement, even dropping the syllable spec).

If you're as blank on space names as me, consider me a one-syllable name that goes with the second initial, because we kind of use that dynamic to call our kids sometimes. For example, Mars would be Mars C. Almost Marcy. Which is kind of cute. I also thought of Quinn C, or Quincy - but to be honest the only association I have with that name is from Daria. And.. God no.
