A star is a massive luminous spheroid astronomical object made of plasma that is held together by its own gravity.Stars exhibit great diversity in their properties (such as mass, volume, velocity, stage in stellar evolution, and distance from Earth) and some of the outliers are so disproportionate in comparison with the general population that they are considered extreme.
This is a list of coolest stars and brown dwarfs discovered, arranged by decreasing temperature. The stars with temperatures lower than 2,000 K are included. Coolest main sequence stars
It is the fourth-closest star or (sub-) brown dwarf system to the Sun and was discovered by Kevin Luhman in 2013 using data from the Wide-field Infrared Survey Explorer (WISE). It is the coldest brown dwarf found in interstellar space, having a temperature of about 285 K (12 °C; 53 °F). [4]
Diagram of stellar evolution, showing the various stages of stars with different masses. A black dwarf is a theoretical stellar remnant, specifically a white dwarf that has cooled sufficiently to no longer emit significant heat or light.
Neutron stars are stellar remnants produced when a star of around 8–9 solar masses or more explodes in a supernova at the end of its life. They are usually produced by stars of less than 20 solar masses, although a more massive star may produce a neutron star in certain cases.

Lies within the Alpha Centauri star system [9] Barnard's Star: Named after its discoverer, E. E. Barnard: Second closest neighbouring star system to Earth, after α Cen. Also the star with the highest proper motion. [14] van Biesbroeck's star: Named for its discoverer, George van Biesbroeck: Was once the least luminous, and, lowest mass, known ...
WHL0137-LS, also known as Earendel, is a star located in the constellation of Cetus.Discovered in 2022 by the Hubble Space Telescope, it is the earliest and most distant known star, at a comoving distance of 28 billion light-years (8.6 billion parsecs).
