Top 1,015 Space Keywords
Monthly search volume, CPC, competition and a 12-month trend for 1,015 space keywords, updated October 2026.
Space keywords are planets, missions, agencies, telescopes and the news-driven searches (launches, eclipses, discoveries). Curiosity and education drive the volume; there is little commercial intent beyond telescopes and merchandise.
The list holds 1,015 keywords with a combined 138,981,730 searches a month. The most searched are starlink (5,000,000), earth (4,090,000), interstellar (3,350,000), sun (3,350,000), nasa (2,740,000), spacex (2,740,000), star (2,740,000), io (2,240,000), jupiter (2,240,000) and nova (2,240,000).
Advertisers pay most for mass driver ($15.49 a click), starburst galaxies ($10.24 a click), star cluster ($6.08 a click), galactic evolution ($6.01 a click) and galaxy formation ($6.00 a click). 8% of the keywords in the list cost $1 or more a click, which marks the commercial end of the niche.
Demand is steady through the year: across the list, the busiest and quietest months are within 1.4x of each other. The trend column shows each keyword's own twelve months.
Volumes are global monthly averages from Google; CPC is the top-of-page bid in US dollars; competition runs from 0 (few advertisers) to 1 (many). Last refreshed October 2026. For any other keyword, the free search volume checker gives the same numbers, and the Keywords Everywhere extension shows them inside Google as you search.
