Perhaps you should try some spelling variations:
"Planetary habitability" » "Planetary variability", "Planetary suitability"
"Planetary excitability" » "Planetary excitabilidad", "Planetary sociability", "Planetary suitability"
"Planetary abailability" » "Planetary availability"
"Planetary habitabilidad" » "Planetary variabilidad"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((((("Planetary habitability") OR ("Planetary excitability"))) OR ("Planetary abailability"))) OR ("Planetary habitabilidad"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"Planetary habitability\") OR (\"Planetary excitability\"))) OR (\"Planetary abailability\"))) OR (\"Planetary habitabilidad\"))".
• Removing quotes may allow a broader search: (((((( Planetary habitability ) OR ( Planetary excitability ))) OR ( Planetary abailability ))) OR ( Planetary habitabilidad )).
• Adding a wildcard symbol may retrieve word variants: (((((("Planetary habitability") OR ("Planetary excitability"))) OR ("Planetary abailability"))) OR ("Planetary habitabilidad"))*.
