Looking for unisex or boys names that are two syllables and end with a vowel, with the preference that they have some outer space significance. For reference the girl name would be [name_u]Vega[/name_u].
[name_m]Pluto[/name_m]
[name_m]Leo[/name_m]
[name_m]Draco[/name_m]
Pavo
[name_u]Yuri[/name_u] (do historical astronauts count?)
Excluding the outer space connection…
[name_u]Ezra[/name_u]
[name_u]Arlo[/name_u]
[name_m]Hugo[/name_m]
[name_m]Jago[/name_m]
[name_u]Levi[/name_u]
[name_u]Milo[/name_u]
[name_m]Otto[/name_m]
[name_u]Nico[/name_u]
[name_u]Sacha[/name_u] / [name_u]Sasha[/name_u]
[name_u]Theo[/name_u]
[name_m]Viggo[/name_m]
They don’t meet the criteria but [name_u]Atlas[/name_u], [name_m]Cyrus[/name_m] or [name_u]Orion[/name_u] would work really well. If not maybe…
[name_u]Nova[/name_u]
[name_f]Cleo[/name_f]
[name_u]Skye[/name_u] ( these may feel to feminine)
[name_u]Valo[/name_u]
[name_u]Halo[/name_u]
[name_m]Helio[/name_m]
[name_m]Elio[/name_m]
[name_m]Miro[/name_m]
[name_m]Cosmo[/name_m]
[name_m]Astro[/name_m]
[name_m]Julio[/name_m]
[name_f]Soleil[/name_f] (French word name)

[name_u]Hoku[/name_u]
[name_m]Cyro[/name_m]

Some of these may have already been mentioned [name_u]Loki[/name_u]
