Star size
Radius of the star 2MASS J22081363+2921215 is not known. Its estimated value based on other similar stars is about 10 % solar radii.

The size of a star refers to its radius — the distance from its center to its surface. Star size is usually measured in solar radii (R☉), where 1 solar radius equals approximately 696,000 kilometers. Depending on their type and life stage, stars can be much smaller or larger than the Sun... icon More about Star size in StellarGuide

Star temperature
Surface temperature of 2MASS J22081363+2921215 is estimated to be 2000 K, which is 35 % of the temperature on the surface of the Sun.

The temperature of a star refers to the temperature at its surface, also called the photosphere. It is measured in kelvins (K), the standard unit for temperature in astronomy. A star’s temperature tells us a lot about its physical properties and where it stands in its evolutionary stage... icon More about Star temperature in StellarGuide

Class of stars Brown dwarf
Brown dwarfs are not really stars, because there is no thermonuclear fusion in their core. These objects are smaller and cooler than stars, but too massive to be considered planets.

A puzzling mass mismatch in the supergiant HD 80077 hints that massive stars may evolve in ways current models cannot fully explain. The latest research also explores how a neutron star’s tilt changes its X-ray light, detects stellar rhythms in infrared observations, and maps cloudy and clear regions on a distant giant planet.
