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.
First evidence for exoplanet to receive later confirmation. First exoplanets to be confirmed PSR B1257+12 B PSR B1257+12 C: PSR B1257+12: 1992 First super-Earths. [1] These exoplanets orbit a pulsar. First confirmed exoplanet around normal star 51 Pegasi b: 51 Pegasi: 1995 First convincing exoplanet discovered around a Sun-like star. [2]
The first such project (NameExoWorlds I), in 2015, regarded the naming of stars and exoplanets. [1] 573,242 votes were submitted by members by the time the contest closed on October 31, 2015, and the names of 31 exoplanets and 14 stars were selected from these. [2] Many of the names chosen were based on world history, mythology and literature. [3]

Initially, the names given to minor planets followed the same pattern as the other planets: names from Greek or Roman myths, with a preference for female names. With the discovery in 1898 of the first body found to cross the orbit of Mars, a different choice was deemed appropriate, and 433 Eros was chosen.
The exoplanet naming convention is an extension of the system used for naming multiple-star systems as adopted by the International Astronomical Union (IAU). For exoplanets orbiting a single star, the name is normally formed by taking the name of its parent star and adding a lowercase letter.

The following is a list of planet types by their mass, orbit, physical and chemical composition, or by another classification. The IAU defines that a planet in the Solar System must orbit around the Sun, has enough mass to assume hydrostatic equilibrium, and has "cleared its neighborhood". The working definition of an exoplanet is as follows ...
