NASA Exoplanets

Confirmed exoplanet discovery counts by year and by detection method, with totals, the peak year and a cumulative series.

Planet size, mass, density, gravity and escape speed as ratios to Earth, with insolation if luminosity and orbit are given.

Planet equilibrium temperature in K, C and F from star luminosity or temperature and radius, orbit distance and albedo.

Habitable-zone edges in AU for a star from luminosity or radius, plus temperature (Kopparapu 2013), and where an orbit falls.

Hill radius of a planet in AU and km from its mass, orbit, eccentricity and star mass, with the stable-moon region.

All confirmed planets of a host star by name, with star properties and each planet's period, size and habitable-zone position.

Closest known exoplanets to the Sun in light-years, optional size filter, with star type, orbit and habitable-zone position.

Habitable-zone screen for a named exoplanet: orbit versus the zone edges, size class and rocky-planet plausibility.

Confirmed exoplanet by name: star, orbit, size, mass, temperature, discovery, Earth ratios and habitable-zone position.

Transit depth (Rp/Rs squared) in percent and ppm from planet and star radius, plus duration if period and star mass are given.
