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.
It is also the third-most massive of the system, with a mass of 1.308 M 🜨, slightly lower than that of the next most massive, TRAPPIST-1g. [2] Initial estimates suggested that TRAPPIST-1c has a lower density (4.89 g/cm 3 ) and gravity (0.966g) than Earth, consistent with a rock-based composition and a thick, Venus-like atmosphere.
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.
This list of exoplanets discovered in 2025 is a list of confirmed exoplanets that were first reported in 2025. For exoplanets detected only by radial velocity , the listed value for mass is a lower limit.
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.

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]
The bright giant star BD+20 2457 was proposed to host two super-Jupiter planets or brown dwarfs, although the claimed planetary system is not dynamically stable. [19] As BD+20 2457 is a halo star possibly having formed in the Gaia Enceladus , which are galactic remains of a former galaxy, the star and its planets might be extragalactic in origin.
As of October 2023, LHS 1140 is known to have two confirmed planets orbiting it. [3] The first to be discovered was LHS 1140 b, discovered by the MEarth Project in 2017 using the transit method. [2] Follow-up radial velocities were measured by the High Accuracy Radial Velocity Planet Searcher instrument to confirm the planet and measure the ...
