KOI-142 - System
Simulates Kepler-88, also KOI-142, nicknamed the king of transit variations. An outer giant yanks the inner transiting planet far off a regular clock.
Exoplanets
Hall of Fame
Landmark exoplanet systems: the first confirmed planets, the discoveries that opened each detection method, and the architectures that changed the field. Pulsar planets, 51 Pegasi, transiting hot Jupiters, imaged giants, circumbinary worlds, and compact chains such as TRAPPIST-1. These systems also remain in their planet-count lists.
KOI-351 - System
Simulates Kepler-90, also called KOI-351, the only eight-planet system known besides possibly our own. Its packed planets rival the Solar System in number.
KOI-94 - System
Simulates Kepler-89, also KOI-94, site of the first seen planet-planet eclipse. One planet was caught partly blocking another as both transited. The overlap was caught in the Kepler light curve.
Kepler-10 - System
Simulates Kepler-10 b, the first rocky exoplanet with a measured density. Kepler's first solid world is a lava planet orbiting in less than a day. A larger outer planet, Kepler-10 c, also transits.
Kepler-11 - System
Simulates Kepler-11, the first compact six-planet system. Six low-density worlds orbit inside the distance of Venus and continually perturb one another.
Kepler-138 - System
Simulates Kepler-138, a low-density system whose outer planets are candidate water worlds. Their masses and radii imply oceans under thick atmospheres.
Kepler-1520 - System
Simulates Kepler-1520 b, a disintegrating planet. A dusty tail trailing this tiny world makes its transits change shape from orbit to orbit. The object is also known as KIC 12557548 b.
Kepler-16 - System
Simulates Kepler-16 b, the first transiting circumbinary planet — a Tatooine world. It eclipses both stars of a close pair as it orbits their barycenter.
Kepler-1625 - System
Simulates Kepler-1625 b, host of the strongest exomoon candidate yet claimed. A Neptune-sized moon has been proposed from Hubble transit residuals, still unconfirmed.
Kepler-1647 - System
Simulates Kepler-1647 b, a gas giant on the longest circumbinary orbit Kepler found. It circles two stars near their shared habitable zone. Its year around the stellar pair lasts about three years.
Kepler-1649 - System
Simulates Kepler-1649 c, an Earth-sized habitable-zone planet missed by the pipeline and recovered by citizen scientists rechecking Kepler false positives.
Kepler-186 - System
Simulates Kepler-186 f, the first Earth-sized planet found in a habitable zone. It is the outermost of five worlds around a cool red dwarf. The red-dwarf host lies about 580 light-years away.
Kepler-19 - System
Simulates Kepler-19, whose unseen outer planet was the first world discovered purely from transit timing. Kepler-19 c never crosses the star itself. Only the inner planet, Kepler-19 b, is seen to transit.
Kepler-20 - System
Simulates Kepler-20, the first system with Earth-sized planets. Kepler-20 e and f alternate with larger worlds in a tight, mixed-size chain. Earth-sized e and f were announced together in 2011.
Kepler-22 - System
Simulates Kepler-22 b, the first planet Kepler found in a habitable zone. This super-Earth-sized world circles a Sun-like star every 290 days. The planet is roughly 2.4 times Earth's radius.
Kepler-223 - System
Simulates Kepler-223, four planets locked in a chain of mean-motion resonances. Their orbits repeat like a gravitational clockwork. Neighboring pairs sit in 4:3, 3:2, and 4:3 resonances.
Kepler-30 - System
Simulates Kepler-30, a resonant three-planet system used to watch starspots. Transits crossing spots measured that the planets and star share one plane.
Kepler-34 - System
Simulates Kepler-34 b, a circumbinary giant orbiting a pair of Sun-like stars. Like Kepler-16, it is a Tatooine world, but around two brighter stars. The planet's year around the pair lasts about 289 days.
