List of candidate multiplanetary systems

candidate exoplanetary systems for the story. These systems are examples of star systems with more than two known planets, though additional planets may be added for fictional purposes if they are below the mass that would be required for modern telescopes to detect them. Gas giants are preferable to super-Earths because gas giants can have (fictional) moons.

YZ Ceti: M4V star. Four hot earth-mass planet. Variable star.
Gliese 876: M4V star. A hot super-earth, two Jupiters (one in the habitable zone), and one Neptunian.
82 G. Eridani: G8V star. Hot dust disk, 2 unconfirmed hot super-Earths, 3 hot super-Earths, and one unconfirmed sub-neptune at hab zone inner limit.
Glise 667 C: M1.5V star, in a trinary with two K dwarfs. Two super-earths, one in the habitable zone.
HR 8832: K3V star. 5-7 hot super-earths.
61 Virginis: G7V star. One hot super-Earth and two hot Neptunians.
TRAPPIST-1: M8V star. Seven earthlike planets. A bit homogenous. 3 in hab zone.
55 Cancri A: G8V star. A burning superEarth, three hot Jupiters, and a normal Jupiter. 55CA-f (Harriot) is in hab zone. All named planets.
HD 40307: K2V star. 6 super Earth planets. Least massive planet is 3.5 Mearth.
Upsilon Andromedae A: F8V star. Four jovian planets. υ And A d (Majriti) is a superjovian in the habitable zone. Inner three are named. System has evidence of planet scattering and thus very strange orbits.
47 Ursae Majoris: G1V star. Three superjovians, innermost is just outside the hab zone. Two are named.
Glise 163: M3V star. Five small gas giants, one super-Earth.
HD 176051: G0V + K1V. One jupiter. Its orbital parent is not known between the two stars--if it is the G0V star, then it is in the habitable zone.
Mu Arae: G3IV. One sub-Neptune, one small Jovian, and two Jovian planets. Mu Arae b (Quijote) and e (Sancho) are in the habitable zone. All named.
Glise 581: M3V star. Five planets (inner three confirmed). Glise 581 g, 2.2Mearth, is in the habitable zone. Planet d is in the outer limits of the system.
Glise 676 A: M0V star. Four planets. A super Earth, a sub-Neptune, and two super-Jupiters.
HD 215152: K3V star. Four Earths of 1.8, 1.7, 2.8, and 2.9 Earth masses. All are scorched.
HD 142: F7V star. Gas giants of 0.3, 1.25, and 5.3 Mjupiter. None in habitable zone.
HIP 57274: K5V. NO DATA about its three planets on wiki.
HD 181433: K5V. Three planets, a super-Earth, two sub-Jupiters. None in hab zone.
HD 82943: F9V. Three gas giant planets. Two at the inner and outer edges of the hab zone.
HD 37124: G4IV. A super-Earth, two sub-Neptunes. Planet c is in the habitable zone.
Kepler-444: K0V. Five tiny hot planets.  Largest is 0.741 Rearth, smallest is 0.4 Rearth.
Kepler-42: M5V. Three planets with radius of 0.73,0.78,0.57 Rearth. All very hot.
HD 10180: G1V. Nine planets. Planet g is in habitable zone. Orbital layout slightly resembles the Bajoran system from Star Trek. all planets except g and h are hot, even scorched.
Kepler-296 A: Five planets with 1.5-2 earth radii. Planets e and f are in the habitable zone.
HR 8799: uh... I have no clue what spectral type this thing is. Seems to be a hot subgiant or dwarf variable. This is the one with the video of the orbiting planets. Four superjupiters in the outer system.
HD 34445: G0V. Six super-Neptune planets. Planets f and b are in the habitable zone.
HD 27894: K2V. Two sub-Jupiters and 1 super-Jupiter.
HIP 14810: G5V. A superjupiter, a jupiter, and a subjupiter. The latter is barely in the optimistic outer edge of the hab zone.
HD 125612: G3V. A neptune and two superjupiters. Planet b is in the cooler parts of the habitable zone.
Kepler-37: G8V. A mesoplanet, an Earth, and a sub-Neptune. All of them are too hot.
HIP 41378: F8V. Five planets: Two sub-Neptunes, two gas giants, and one Neptune. All are too hot.
Kepler-68: G2IV. Three planets. Planet d is in the habitable zone and is a Jupiter.
Kepler-186: M1V. Five planets, all with Earthlike radii. Planet f is borderline habitable, others are too hot.
WASP-47: G9V. Four planets. A superEarth, a Jupiter, a Neptune, and a Superjupiter. The latter is in the habitable zone, the others are much closer in and much hotter.
Kepler-20: G8V. Six hot planets.
PSR B1257+12: Pulsar. Three named planets. A moonlike body, two super Earths. Pulsars have no habitable zone!!!
