Proper names of planetary systems often follow common themes – for example, the planets of the star Copernicus are named after European astronomers. Proper names for planets outside of the Solar System – known as exoplanets – are chosen by the International Astronomical Union (IAU) through public naming contests known as NameExoWorlds.
The International Astronomical Union has assigned proper names to some known extrasolar bodies, including nearby exoplanets, through the NameExoWorlds project. Planets named in the 2015 event include the planets around Epsilon Eridani (10.5 ly) and Fomalhaut , [ note 4 ] [ 10 ] while planets named in the 2022 event include those around Gliese ...
The most distant potentially habitable planet confirmed is Kepler-1606b, at 2870 light-years distant, [2] although the unconfirmed planet KOI-5889.01 is over 5000 light-years distant. On 31 March 2022, K2-2016-BLG-0005Lb was reported to be the most distant exoplanet discovered by the Kepler telescope , at 17 000 light-years away.
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 1007 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).
There are eight planets within the Solar System; planets outside of the solar system are also known as exoplanets. Artist's concept of the potentially habitable exoplanet Kepler-186f As of 19 December 2024, there are 5,811 confirmed exoplanets in 4,340 planetary systems , with 973 systems having more than one planet .

It differs from the “light travel distance” since the proper distance takes into account the expansion of the universe, i.e. the space expands as the light travels through it, resulting in numerical values which locate the most distant galaxies beyond the Hubble sphere and therefore with recession velocities greater than the speed of light c.

The nearest such planet was then as close as 12 light-years away [7] [8] but (see below) is now estimated slightly above four light-years away. On August 24, 2016, astronomers announced the discovery of a rocky planet in the habitable zone of Proxima Centauri, the closest star to Earth (not counting the
