List of planetary systems

List of planetary systems
Number of extrasolar planet discoveries per year as of 7 July 2011, with colors indicating method of detection:

The following are the 53 known planetary systems (i.e. stars with at least two confirmed planets), including the Solar System, sorted by distance of the host star. The star table below contains information about the coordinates, spectral and physical properties, and number of confirmed planets. The two most important stellar properties are mass and metallicity because it determines how these planetary systems form. The higher mass and metallicity tend to have more planets and more massive planets.

There are 34 stars with two planets, 10 with three, 5 with four, 1 with five, 2 with six, 0 with seven, and 1 with eight. The star with the most confirmed planets is Sol, which contains 8 confirmed planets. The star with most confirmed exoplanets are HD 10180 and Kepler-11, both containing 6 confirmed planets.

Planetary systems

Coloured rows indicate stars with at least three planets.
