Close binary pair (yellow, orange) with distant red dwarf companion; the brightest star (Alpha Centauri A) is similar to the Sun but older and more metallic; terrestrial planets are possible but so far not detected MORE

Young orange star with a massive outer debris disk, two inner asteroid belts, and one Jupiter-size planet at about 3.4 AU; closest exoplanetary system to the Sun. MORE

Mature yellow star with extensive debris belt and potential planets within 10 AU, where debris has been swept out. MORE

Red dwarf with a single Hot Neptune planet 11 times as massive as Earth in a somewhat eccentric orbit. MORE

Red dwarf with 3 known planets; the innermost is one of the smallest exoplanets yet detected, with 7.5 Earth masses; the outer 2 are gas giants in a mean motion resonance. MORE

Red dwarf with one gas giant about 60% as massive as Jupiter in a low-eccentricity orbit at 3.4 AU; potential host for icy exomoons

Red dwarf with 4 planets: one Hot Earth, one Hot Neptune, and two Super Earths whose orbits bracket the system's habitable zone. MORE

White star 2.3 times more massive and 37 times brighter than the Sun; rotating once every 12.5 hours, so fast that it bulges 23% wider at the equator than at the poles; extensive debris disk and planetary candidates. MORE

White star with fast rotation and one gas giant planet orbiting just inside a dusty, sharply defined debris ring. MORE

Relatively massive red dwarf, more metallic than the Sun, with a Jupiter twin at 2.35 AU in a low-eccentricity orbit; potential host for icy exomoons. MORE

Red dwarf with one transiting Hot Neptune; additional stable orbits may be possible in the habitable zone. MORE

Wide binary pair with 5 planets orbiting the G star; 3 are within 0.24 AU; the fifth, with 4 times Jupiter's mass, orbits at 5.8 AU and may host a family of moons. MORE

Orange star with three Neptune-mass planets orbiting within 0.63 AU and a dusty asteroid belt beyond 1 AU. MORE

Orange star with three Super Earths orbiting well starward of the system's habitable zone. MORE

Also HD 9826; wide binary system with 3 giant planets orbiting the F star, which is brighter and more massive than the Sun; the outer planet, with 3.75 times Jupiter's mass, occupies the habitable zone and may host a family of moons. MORE

Also Errai and HD 222404; mature binary system with semimajor axis of 19 AU and period of 67 years; the orange subgiant star, with almost 5 times the Sun's diameter, has one planet at least 1.5 times Jupiter's mass orbiting at 2 AU; potential host for exomoons. MORE

Yellow star -- brighter, larger, and older than the Sun -- with 3 giant planets beyond the habitable zone in unusually circular obits; potential hosts for icy exomoons. MORE

Also HD 160691; one Hot Neptune or Hot Super-Earth, plus 3 giant planets in wider orbits that are potential hosts for exomoons. MORE

Also HD 190360; triple system with yellow subgiant and distant pair of M stars; one Hot Neptune and one gas giant at 4 AU with more than 1.5 times Jupiter's mass. MORE

Also HD 99492; binary system with one planet twice the mass of Neptune in a tight orbit around the K2 star. MORE

Also HD 27442; binary system consisting of an orange subgiant with 5 times the luminosity and 6 times the diameter of the Sun, plus a white dwarf at 240 AU; the subgiant harbors one Jupiter-mass planet at 1.27 AU that may host a family of moons. MORE

Young white star with massive debris disk 10 times the diameter of the Solar System; several planets are likely but remain unconfirmed. MORE

One Hot Jupter and a second planet with more than twice Jupiter's mass in a highly eccentric orbit at a distance of more than 4 AU. MORE
