Star mass
The mass of the star V2213 Ophiuchi is unknown. Based on its other characteristics, it is estimated to be about 120 % of the Sun's mass.

The mass of a star is the total amount of matter it contains. It is one of the most important properties of a star, as it determines almost everything about how the star lives, changes, and dies. In astronomy, star mass is usually measured in solar masses (M☉) — where 1 solar mass is equal to the mass of our Sun... icon More about Star mass in StellarGuide

Star size
Radius of the star V2213 Ophiuchi is not known. Its estimated value based on other similar stars is about 220 % 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 V2213 Ophiuchi is estimated to be 5917 K, which is 102 % 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

 V2213 Ophiuchi

More about V2213 Ophiuchi

      a BY Draconis variable. Stars from this category exhibit periodic variations in their luminosity. The variability is caused by a rotation which shows and hides starspots on the surface. V2213 Ophiuchi can be found in northern celestial hemisphere, you cannot see it with naked eye, but you can observe this star with basic telescope. The star is easily observable from Northern America, Europe and Asia. 

      V2213 Ophiuchi is a BY Draconis variable. Stars from this category exhibit periodic variations in their luminosity. The variability is caused by a rotation which shows and hides starspots on the surface.
