{{Short description|A list of systems with multiple planets}} | |||
The following are lists of stars with confirmed ]s. Note that the masses of the ]s are (for the most part) lower bounds only. If a planet is detected by the ] displacement method, no information is gained about the ] of the planet's plane of ] around its star, and a value for this is needed to calculate the mass. It has become customary to arbitrarily assume that the plane is exactly lined up with the line of sight from Earth (this produces the lowest possible mass consistent with the spectral line measurements). The planets are listed with indications of their approximate masses as multiples of ]'s mass (M<sub>J</sub> = 1.898 x 10<sup>27</sup> kg) or multiples of ]'s mass (M<sub>E</sub> = 5.9737 x 10<sup>24</sup> kg), and some also have approximate distances in ]s (1 AU = 1.496 x 10<sup>8</sup> km) from their parent stars. For more information on how planets may be detected, see ]. | |||

The table below contains information about the coordinates, spectral and physical properties, and the number of confirmed (unconfirmed) planets for systems with at least 2 planets and 1 not confirmed. The two most important ] are ] and ] because they determine how these ]s form. Systems with higher mass and metallicity tend to have more planets and more massive planets. However, although low metallicity stars tend to have fewer massive planets, particularly hot-Jupiters, they also tend to have a larger number of close-in planets, orbiting at less than 1 AU.<ref name="JMBrewer2018">{{cite journal |last1=Brewer |first1=John M. |last2=Wang |first2=Songhu |last3=Fischer |first3=Debra A. |last4=Foreman-Mackey |first4=Daniel |title=Compact multi-planet systems are more common around metal poor hosts|journal=The Astrophysical Journal |volume=867 |at=L3 |arxiv=1810.10009 |doi=10.3847/2041-8213/aae710 |date=2018-10-24 |issue=1 |bibcode=2018ApJ...867L...3B |s2cid=67832557 |doi-access=free }}</ref> | |||

A list of systems with multiple planets Further information: Planetary systemDirect imaging Microlensing Transit Radial velocity Timing |
From the total of 4,949 stars known to have exoplanets (as of July 24, 2024), there are a total of 1007 known multiplanetary systems, or stars with at least two confirmed planets, beyond the Solar System. This list includes systems with at least three confirmed planets or two confirmed planets where additional candidates have been proposed. The stars with the most confirmed planets are the Sun (the Solar System's star) and Kepler-90, with 8 confirmed planets each, followed by TRAPPIST-1 with 7 planets.
The 1007 multiplanetary systems are listed below according to the star's distance from Earth. Proxima Centauri, the closest star to the Solar System, has three planets (b, c and d). The nearest system with four or more confirmed planets is Gliese 876, with four known. The farthest confirmed multiplanetary system is OGLE-2012-BLG-0026L, at 13,300 light-years (4,100 pc) away.
The table below contains information about the coordinates, spectral and physical properties, and the number of confirmed (unconfirmed) planets for systems with at least 2 planets and 1 not confirmed. The two most important stellar properties are mass and metallicity because they determine how these planetary systems form. Systems with higher mass and metallicity tend to have more planets and more massive planets. However, although low metallicity stars tend to have fewer massive planets, particularly hot-Jupiters, they also tend to have a larger number of close-in planets, orbiting at less than 1 AU.
