From the total of 5,086 stars known to have exoplanets (as of January 26, 2024), there are a total of 1,033 known multiplanetary systems, [1] 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.
Kepler-9 holds the first multiplanetary system discovered using the transit method. It is also the first planetary system where transiting planets were confirmed through transit timing variations method, allowing to calculate the masses of planets. [10] The discovery of the planets was announced on August 26, 2010. [9]
This is a list of space probes that have left Earth orbit (or were launched with that intention but failed), organized by their planned destination. It includes planetary probes, solar probes, and probes to asteroids and comets, but excludes lunar missions, which are listed separately at List of lunar probes and List of Apollo missions.
This list contain only confirmed planets. Many candidate planets were decected via astrometry, including Gliese 65 Ab (which would be the nearest planet detected by this method, if confirmed), 9,698 candidates shown in a paper [1] as well as many more detected via Hipparcos-Gaia astrometry in another studies.

An artist's rendition of Kepler-62f, a potentially habitable exoplanet discovered using data transmitted by the Kepler space telescope. The list of exoplanets detected by the Kepler space telescope contains bodies with a wide variety of properties, with significant ranges in orbital distances, masses, radii, composition, habitability, and host star type.
The most massive exoplanet candidate is HD 217786 b, which masses 12.98 M J; the least massive confirmed planet is HD 10180 b, which masses 0.004 M J or 3.1 M 🜨. 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 ...
