Star mass
Mass of the star Gamma Virginis B is 1.5 solar masses.

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 Gamma Virginis B is not known. Its estimated value based on other similar stars is about 170 % 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 Gamma Virginis B is estimated to be 7272 K, which is 126 % 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

Working with real data
icon Data in Stellar Catalog come from trusted scientific sources. Primary source is Gaia space telescope mapping the stars in Milky Way. Other sources include research papers, Simbad catalog and Exoplanet.eu database.
Estimated values
icon Objects listed in the Stellar Catalog often have values that are estimates. These estimates are determined using their known characteristics, such as spectral type, brightness across different wavelengths, distance from a star, and other factors.
Fresh and validated
icon Stellar Catalog is continuously updated with new information from research papers. Stellar and planetary data are validated by automatic processes as well as humans.
Get your next news from nearby stars
Stellar Catalog brings the stars from our galaxy to you. Discover their position, physical properties and whether there are any exoplanets or disks orbiting them. The data in Stellar Catalog come from respectable sources like Gaia space telescope, or SIMBAD database.
