Clerics
The PHB gods found in space are listed in AA in a background:
Corellon (elves)
Tymora (good fortune)
Fharlanghn (roads)
Istus (Fate/destiny)
Nuada (War and Warriors)
Zivilyn (DL:Wisdom)
Arawn (Life and Death)
Hecate (Magic and Moon)
Celestian (Astral/Space)
Path (opener of the ways)
And, of course, where there are dwarves, there are Moradin clerics. Probably the only Forge Clerics in Space, as fires in air envelopes tend to burn up all the air. Besides, none of the Space gods are Forge types.
Note that Celestian and Ptah date back to the old edition, and are likely most common, while Hecate is actually a Moon god, and probably less common.
