- #1 OGLE-2005-BLG-169L — --9,223,372,036,854,775,808 kg
star
OGLE-2005-BLG-169L is a dim and distant magnitude 20 galactic bulge star located about 2,700 parsecs away in the constellation Sagittarius. If it is a main sequence star, then it is most likely a red dwarf with about half of the mass of the Sun. Other possibilities are a white dwarf star, or a neutron star or black hole.

Wikidata - #2 Kepler-61 — --9,223,372,036,854,775,808 kg
star in the constellation Cygnus
Kepler-61 is a K-type main-sequence star approximately 1,100 light years from Earth in the constellation Cygnus. It is located within the field of vision of the Kepler spacecraft, the satellite that NASA's Kepler Mission used to detect planets that may be transiting their stars. On April 24, 2013 it was announced that the star has an extrasolar planet orbiting in the inner edge of the habitable zone, named Kepler-61b. Read more on Wikipedia.
Wikidata - #3 NGTS-1 — --9,223,372,036,854,775,808 kg
star in the constellation Columba
NGTS-1, also designated as TOI-551 is a solitary star located in the southern constellation Columba, the dove. With an apparent magnitude of 15.52, NGTS-1 can only be seen through a powerful telescope. Gaia DR3 parallax measurements imply a distance of 710 light-years and it is drifting away rapidly with a heliocentric radial velocity of 97.2 km/s. Read more on Wikipedia.
Wikidata - #4 K2-3 — --9,223,372,036,854,775,808 kg
red dwarf
K2-3, also known as EPIC 201367065, is a red dwarf star with three known planets. It is on the borderline of being a late orange dwarf/K-type star, but because of its temperature, it is classified as a red dwarf. Read more on Wikipedia.

red dwarfstar
Kepler-438 is a red dwarf in the constellation Lyra, about 590 light years from Earth. It is notable for its planetary system, which includes Kepler-438b, a possibly Earth-size planet within Kepler-438's habitable zone. Kepler-438 is a flare star that undergoes random, dramatic increases in brightness due to flare activity. It emits strong superflares every few hundred days, with each flare being stronger than the most powerful flare recorded on the Sun. Read more on Wikipedia.
Wikidata - #7 Gliese 649 — --9,223,372,036,854,775,808 kg
star
Gliese 649 is a small star with an orbiting exoplanet in the constellation Hercules. It has an apparent visual magnitude of 9.7, which is too faint to be seen with the naked eye. The system is located at a distance of 33.9 light years based on parallax, and is drifting further away with a radial velocity of 3.8 km/s. Read more on Wikipedia.
Wikidata - #8 AU Microscopii — --9,223,372,036,854,775,808 kg
star in the constellation Microscopium
AU Microscopii is a young red dwarf star located 31.7 light-years away – about 8 times as far as the closest star after the Sun. The apparent visual magnitude of AU Microscopii is 8.73, which is too dim to be seen with the naked eye. It was given this designation because it is in the southern constellation Microscopium and is a variable star. Like β Pictoris, AU Microscopii has a circumstellar disk of dust known as a debris disk and at least three exoplanets, with the presence of an... Read more on Wikipedia.

star
Kepler-138, also known as KOI-314, is a red dwarf located in the constellation Lyra, 219 light years from Earth. It is located within the field of vision of the Kepler spacecraft, the satellite that NASA's Kepler Mission used to detect planets transiting their stars. Read more on Wikipedia.
Wikidata - #10 Kepler-186 — --9,223,372,036,854,775,808 kg
star in the constellation Cygnus
Kepler-186 is a red dwarf star, located 177.5 parsecs away in the constellation of Cygnus. The star is slightly cooler than the Sun, with roughly half its metallicity. It is known to have five planets, including the first Earth-sized planet discovered in the habitable zone: Kepler-186f. The star hosts four other planets discovered so far, though they all orbit interior to the habitable zone. Read more on Wikipedia.
