A list of systems with multiple planets Further information: Planetary system
Number of extrasolar planet discoveries per year through 2023. Colors indicate method of detection.
  Direct 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.

Multiplanetary systems

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources.
