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 1,033 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).
A multiple star system consists of two or more stars that appear from Earth to be close to one another in the sky. [dubious – discuss] This may result from the stars actually being physically close and gravitationally bound to each other, in which case it is a physical multiple star, or this closeness may be merely apparent, in which case it is an optical multiple star [a] Physical multiple ...

The planets orbit their central star in a rhythmic beat, a rare case of an ‘in sync’ gravitational lockstep.
If confirmed, this would be the only known star with a multi-planet system entirely comprised of planets smaller than Earth. Barnard's star, in the constellation Ophiuchus, has a mass about 16% of ...

Kepler-47 is the first circumbinary multi-planet system discovered by the Kepler mission. [5] The outermost of the planets is a gas giant orbiting within the habitable zone of the stars. [6] Because most stars are binary, the discovery that multi-planet systems can form in such a system has impacted previous theories of planetary formation. [7] [5]
The longest period of any confirmed exoplanet is 47 Ursae Majoris d, which takes 14002 days or 38.33 years to make one trip around the star; the shortest period is HD 156668 b, which takes just 1.26984 days or 31.162 hours to orbit the star. Yellow rows denote the members of a multi-planet system
