ExoSky
An interactive 3D atlas of confirmed exoplanets and exomoon candidates like CD-35 2722 b, with plain-language stories of what astronomers think each world is like.
Amateur astronomy enthusiasts who want more than a star chart — they want stories about distant worlds
- Tap any catalogued exoplanet or exomoon candidate for size, orbit, host star, and discovery method
- AI-generated 'what it might be like' narrative based on mass, temperature, and star type
- AR mode that points your phone at the night sky to show where the host star sits
- Weekly update feed whenever a new exomoon candidate is announced
Article announces a potential first exomoon around the brown dwarf in CD-35 2722 — exactly the kind of milestone that drives hobbyist interest in exoworlds.
CD-35 2722 exomoon candidate generated genuine buzz (Nature paper, HN 142pts, Mashable/Space.com/Physics World coverage), but the target audience — amateur astronomy enthusiasts wanting 'stories' — is a small subset of a niche hobby.Planetary-mass exosatellite detected around the substellar companion CD-35 2722 B — Nature ↗Astronomers think they've discovered a giant moon in another star system — Mashable ↗
Market is already crowded with direct competitors offering interactive 3D exoplanet atlases: exoplanetatlas.com (6,000+ planets, 3D viz, NASA data), exoseeker.github.io, cosmolapse.com, thekuiperspace.com, and space.pointdynamics.com — only the narrative/story angle is differentiated and easily copied.Exoplanet Atlas — Explore Thousands of Worlds Beyond Our Solar System ↗CosmoLapse, an interactive 3D atlas of the cosmos ↗
No evidence of willingness to pay; exoplanetatlas.com and competing sites are free with only newsletter signups, and the hobbyist astronomy crowd is notoriously price-sensitive with abundant free alternatives.Exoplanet Atlas — Explore Thousands of Worlds Beyond Our Solar System ↗
Exoplanet catalog is in growth phase — exoplanetatlas.com shows new discoveries (TOI-5789 c, HD 85426 c, etc.) added regularly, James Webb and ground-based surveys continue expanding the catalog, and each milestone like CD-35 2722 renews public interest.Exoplanet Atlas — Explore Thousands of Worlds Beyond Our Solar System ↗
Build is technically straightforward (Three.js + NASA Exoplanet Archive API, which is free/public), but the real bottleneck is authoring plain-language 'stories' for 6,000+ worlds — a massive content burden that doesn't scale without LLM-generated copy.
