List of multiplanetary systems
Wikimedia list article
From the total of 4,809 stars known to have exoplanets (as of 23 April 2026), there are a total of 1,061 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 eight confirmed planets each, followed by TRAPPIST-1 with seven planets.
The multiplanetary systems are listed below according to the star's distance from Earth. Proxima Centauri, the closest star to the Solar System, has at least two planets (the confirmed b, d and the disputed c). The nearest system with four or more confirmed planets is Barnard Star, with four known. The farthest confirmed system with two or more planets 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 two planets and one 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.
The public source identifies “List of multiplanetary systems” as wikimedia list article. This brief keeps that definition visible, then builds a research path around List, multiplanetary and systems.
Why this record matters
A short description can identify a subject without explaining its stakes. For “List of multiplanetary systems”, the useful work is to connect “wikimedia list article” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q14606370. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2026 and 2012.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
