Confirmed exoplanets by methods EPE
Number of extrasolar planet discoveries per year through 2023. Colors show how they were found.

Imagine looking up at the night sky and seeing not just our Sun with its eight planets, but many other stars with their own families of planets! These are called exoplanets, and when a star has more than one, it's a multiplanetary system.

As of September 1, 2023, scientists have found planets orbiting 4,065 stars. Out of these, 878 are multiplanetary systems. This means they have at least two confirmed planets. Some even have more! Our Sun's system and Kepler-90 both have 8 confirmed planets, which is the most found so far. TRAPPIST-1 is close behind with 7 planets.

These amazing systems are listed below, starting with the ones closest to Earth. The nearest star with planets is Proxima Centauri, which has three planets. The closest system with four or more planets is Gliese 876. The farthest one we know about is OGLE-2012-BLG-0026L, which is super far away at about 13,300 light-years!

Scientists study a star's properties, like its mass and how much metal it contains (called metallicity). These things help us understand how planets form around that star. Stars with more mass and metal often have more planets, and bigger ones too. However, stars with less metal might have more planets orbiting very close to them.
