Sagittarius is a constellation in the night sky, not a physical object like a star or a planet, so it does not have a surface temperature.
the color of stars with the lowest surface temperature is red
the color of stars with the lowest surface temperature is red
The Color of stars depends upon their surface temperature.
The color is basically an indication of its surface temperature.
The hottest star in the constellation Sagittarius is generally considered to be the massive blue supergiant known as Eta Sagittarii. Its surface temperature is estimated to be around 30,000 to 40,000 Kelvin, making it one of the hottest stars visible from Earth. This extreme temperature contributes to its brightness and significant ultraviolet radiation.
The stars in the constellation Hercules vary in color from blue to yellow to red, depending on their temperature. The surface temperature of stars in Hercules typically ranges from 3,000 to 30,000 degrees Celsius.
