This was once the smallest known actively fusing star, when found in 2005, through 2013. It is the smallest eclipsing red dwarf, and smallest observationally measured diameter. [101] [102] [103] CoRoT-15b: 82,200 Brown dwarf [104] VB 10: 82,300 Red dwarf: It was the smallest known star from 1948 to 1981. [105] TRAPPIST-1: 82,925
EBLM J0555-57 is a triple star system approximately 670 light-years from Earth. The system's discovery was released on July 12, 2017. EBLM J0555-57Ab, the smallest star in the system, orbits its primary star with a period of 7.8 days, and currently is the smallest known star with a mass sufficient to enable the fusion of hydrogen in its core.
The size of the star was obtained using asteroseismology; [7] Kepler-37 is currently the smallest star to be studied using this process. [6] This allowed the size of Kepler-37b to be determined "with extreme accuracy". [6] To date, Kepler-37b is the smallest planet discovered around a main-sequence star [b] outside the Solar System.

The following is a list of particularly notable actual or hypothetical stars that have their own articles in Wikipedia, but are not included in the lists above. BPM 37093 — a diamond star; Cygnus X-1 — X-ray source; EBLM J0555-57Ab — is one of the smallest stars ever discovered. GY Andromedae — chemically peculiar variable star
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.
The James Webb Space Telescope has captured new detailed portraits of 19 spiral galaxies filled with millions of stars ... Bubbles and filaments are resolved down to the smallest scales ever ...
For the first time ever, the Hubble Space Telescope spotted an individual main sequence star at 9 billion light-years away. That's just a couple billion years after the Big Bang.
LHS 2065 is a red dwarf star, one of the smallest stars ever found with around 8.2% the mass of the Sun and a diameter only 10% greater than Jupiter. [6] It is one of the few ultracool dwarfs known to have flare activity, emmiting one flare every 33 hours, [5] and is also an active X-ray emitter.
