Quasi-stars are predicted to have surface temperatures limited to about 4,000 K (3,730 °C), but, with diameters of approximately 10 billion kilometres (66.85 au) or 7,187 times that of the Sun, each one would produce as much light as a small galaxy.
Kvázi-hviezdy mali približné povrchové teploty obmedzené na cca 4 000 K (3 730 °C), ale s priemerom približne 10 miliárd kilometrov (66,85 au) alebo 7 187 krát priemeru Slnka, by každá z nich produkovala toľko svetla ako malé galaxie.
