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
Universe Sandbox is a series of interactive space sandbox gravity simulator educational software video games.Using Universe Sandbox, users can see the effects of gravity on objects in the universe and run scale simulations of the Solar System, various galaxies or other simulations, while at the same time interacting and maintaining control over gravity, time, and other objects in the universe ...
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.
This makes this star one of the smallest and coolest main sequence stars. [2] It has a stellar classification of L2.5 and a V−K color index of 9.42. [ 2 ] The mass is estimated to be 67.54 ± 12.79 M J ( 0.0644 ± 0.0122 M ☉ ), [ 6 ] though the CARMENES input catalogue estimates a mass around 103 M J . [ 5 ]
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.

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.
With a mass only 93 times that of Jupiter (M J), or .09 M ☉, AB Doradus C, a companion to AB Doradus A, is the smallest known star undergoing nuclear fusion in its core. [12] For stars with similar metallicity to the Sun, the theoretical minimum mass the star can have, and still undergo fusion at the core, is estimated to be about 75 M J.
Willman 1 is an ultra low-luminosity dwarf galaxy or a star cluster. [3] Willman 1 was discovered in 2004 and is located near Ursa Major in the night sky. [4] [5] It is named after Beth Willman of Haverford College, the lead author of a study based on the Sloan Digital Sky Survey data. [6]
