Star size
Radius of the star Gaia DR2 4155202364362108544 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 Gaia DR2 4155202364362108544 is estimated to be 2151 K, which is 38 % 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

A helium plume racing ahead of TOI-3884 b and infrared flickers from WASP 121 reveal surprising details about distant worlds and their stars. New work also maps the cloudy weather of WASP-43 b and traces massive HD 74371’s return to a blue-supergiant phase, while search interest highlights Proxima Centauri, Alpha Centauri, and other stellar favorites.
