The first report of an exoplanet within this range was in 1998 for a planet orbiting around Gliese 876 (15.3 light-years (ly) away), and the latest as of 2024 is one around Struve 2398 A (11.5 ly). The closest exoplanets are those found orbiting the star closest to the Solar System, which is Proxima Centauri 4.25 light-years away
In May 2016, the finding of three Earth-like planets of ultracool dwarf TRAPPIST-1 has been released. The existence of the planet Gliese 832 c was refuted in 2022, when a study found that the radial velocity signal shows characteristics of a signal originating from stellar activity, and not from a planet.

The exoplanets were found using a statistical technique called "verification by multiplicity". 95% of the discovered exoplanets were smaller than Neptune and four, including Kepler-296f, were less than 2 1/2 the size of Earth and were in habitable zones where surface temperatures are suitable for liquid water.

The star is one of a binary pair, so the planet orbits the primary star, while the primary star orbits a secondary star. ... Astronomers have found more than 5,600 confirmed exoplanets, and 300 to ...
In many cases it is not possible to have an exact value, and an estimated range is instead provided. The coldest and oldest planet directly imaged is Epsilon Indi Ab, which has six times Jupiter's mass, an effective temperature of 275 K, and an age of about 3.5 Ga. This list includes the four members of the multi-planet system that orbit HR 8799.
Imaged near Alpha Centauri A: COCONUTS-2b: 6.3 +1.5 −1.9: 400000000 ... Two more planets were previously known; host star also known as EPIC 211413752. [12] K2-268e:
The planet is about the size of Venus, so slightly smaller than Earth, and may be temperate enough to support life, the researchers said. Dubbed Gliese 12 b, the planet takes 12.8 days to orbit a ...
The planets were detected by observing small dips in the star's brightness when they crossed in front of it from our vantage point. The innermost planet takes about nine days to orbit the star ...
