Kepler-35 - System
Simulates Kepler-35 b, a Saturn-sized planet orbiting two stars. Its transits of both stars helped prove circumbinary planets are common, not flukes. Both stars are smaller and cooler than the Sun.
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.
Kepler-36 - System
Simulates Kepler-36, where a rocky world and a puffy mini-Neptune orbit only 0.01 AU apart. Their transit times swing wildly from the mutual tugs. Their bulk densities differ by nearly a factor of eight.
Kepler-37 - System
Simulates Kepler-37, famous for Kepler-37 b, announced as a planet smaller than Mercury. The inner world is one of the tiniest Kepler ever found. The host is a bright G dwarf, so the tiny dips were hard-won.
Kepler-38 - System
Simulates Kepler-38 b, one of the smallest circumbinary planets found by Kepler. It orbits a stellar pair just outside the zone where orbits go unstable.
Kepler-413 - System
Simulates Kepler-413 b, a circumbinary planet whose transits turn on and off. Rapid orbital precession makes the planet miss the stellar disks for years.
Kepler-42 - System
Simulates Kepler-42, three planets smaller than Earth around a tiny red dwarf. The whole system would fit well inside Mercury's orbit. All three planets are smaller than Earth itself.
Kepler-442 - System
Simulates Kepler-442 b, one of the most Earth-like planets Kepler found. It sits in the habitable zone of a K dwarf with a size close to Earth's. It receives about two-thirds of the sunlight Earth gets.
Kepler-444 - System
Simulates Kepler-444, an ancient compact system about 11 billion years old. Five sub-Earth planets orbit a star that formed when the Galaxy was young.
Kepler-452 - System
Simulates Kepler-452 b, called Earth's older cousin. It is a super-Earth in the habitable zone of a Sun-like star somewhat older than the Sun. It receives only modestly more starlight than Earth.
Kepler-453 - System
Simulates Kepler-453 b, a circumbinary giant that only transits about 9 percent of the time. Precession carries it in and out of our line of sight. Most seasons the planet misses the stars entirely.
Kepler-47 - System
Simulates Kepler-47, the first multi-planet system around two stars. At least one of its circumbinary worlds sits near the binary's habitable zone. The stellar pair itself eclipses about every week.
Kepler-51 - System
Simulates Kepler-51, the super-puff system. These planets are nearly as large as Jupiter but only a few Earth masses — cotton-candy densities. Planets b, c, and d are all super-puffs.
Kepler-56 - System
Simulates Kepler-56, the first multi-planet system found tilted relative to its star. The planets share a plane that is tipped against the stellar equator.
Kepler-60 - System
Simulates Kepler-60, three planets hovering near a three-body resonance. Small shifts in spacing would decide whether the chain holds or goes chaotic.
Kepler-62 - System
Simulates Kepler-62, a five-planet system with two worlds in the habitable zone. Kepler-62 f was an early favorite in the search for temperate rocky planets.
Kepler-78 - System
Simulates Kepler-78 b, an Earth-sized lava world with both a measured mass and radius. It orbits so close that a year lasts only 8.5 hours. Its density is close to Earth's, so the planet is rock.
Kepler-79 - System
Simulates Kepler-79, four low-density planets near resonance. Like Kepler-51, they are puffier than their masses suggest, a clue to thick atmospheres.
Kepler-80 - System
Simulates Kepler-80, a compact resonant chain of five planets. Neighboring orbits are so close that transit timing reveals their masses. Transit timing of the chain yields several of the masses.
