More about Vega

Nearby star Vega is a main sequence star that fuses hydrogen atoms into helium. It is is approximately 3 times bigger than the Sun and temperature on its surface is around 9830 K (9557 °C), which is about 170 % of Sun's temperature.

      a pulsating star belonging to the Delta Scuti category. These stars expand and contract with a period in mere hours.  Vega can be found in northern celestial hemisphere, and it is possible to see it with naked eye. The star is easily observable from Northern America, Europe and Asia.

About Stellar Catalog

Working with real data

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

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

Stellar Catalog is continuously updated with new information from research papers. Stellar and planetary data are validated by automatic processes as well as humans.
