Star color is a function of surface temperature 🌟 🔴 The color indicates how hot the visible "surface" of the star is. The coolest stars are red, with surface temperatures of about 3,000ºC. 🔵 As a star's temperature rises, because there is more gas in the star — and therefore more fuel to burn — it becomes hotter. Its color changes from orange to yellow to white. The hottest stars are blue, with temperatures up to 40,000ºC. Explore the stars and other celestial objects with the Sky Tonight app

Color and temperature of the stars. Stars are formed from clouds of gas and dust that, as they contract, heat up and radiate heat and light. But not all stars are created equal. We can establish relationships between the color we see and the temperature of a star. Check it out: Stars defined with colors Red stars Have surface temperature between 3,000°C; Orange stars - On the surface, its temperature is between 4,000°C; Yellow stars - Surface temperature of more or less 6,000°C; White stars - Ar
