4 tools expose this connector's capabilities to your AI agent.

get_planet_stats

Shows how exoplanet science has exploded since Kepler's launch in 2009. Get globalThis exoplanet discovery statistics: totals, methods, yearly trends

get_habitable_zone

These are the most promising candidates for life. Get exoplanets in the habitable zone — where liquid water could exist

get_transit_planets

Transit is the most productive method (>75% of all discoveries). Kepler and TESS are the primary transit missions. Get exoplanets discovered via the transit method (Kepler/TESS)

query_confirmed_planets

Filter by planet name, discovery method (Transit, Radial Velocity, Imaging, Microlensing), discovery facility (Kepler, TESS, Keck), or year. Returns orbital period, radius, mass, equilibrium temperature. Search confirmed exoplanets by name, discovery method, facility, or year

Show me planets in the habitable zone

🌍 **Habitable Zone Candidates** | Planet | Radius (R⊕) | Temp (K) | Method | Year | |--------|------------|----------|--------|------| | TRAPPIST-1 e | 0.92 | 251 | Transit | 2017 | | TRAPPIST-1 f | 1.05 | 219 | Transit | 2017 | | Kepler-442 b | 1.34 | 233 | Transit | 2015 | | TOI-700 d | 1.19 | 268 | Transit | 2020 | Rocky planets (< 2 R⊕) with 200-320K equilibrium temperature.

The habitable zone ('Goldilocks zone') is the range of distances from a star where liquid water could exist on a planet's surface — not too hot, not too cold. We filter for equilibrium temperatures between 200-320K and rocky sizes (< 2 Earth radii).
