SOLAR SYSTEM

Detailed explanation-1: -Yellow stars are hotter than red stars. White stars are hotter than red and yellow. Blue stars are the hottest stars of all.

Detailed explanation-2: -The energy of the blue star is therefore more than the energy of the Sun (since it is inversely proportional). Therefore, the temperature of the star will be greater than the temperature of the Sun, i.e., the star which appears blue will be much hotter than the Sun.

Detailed explanation-3: -Stars are different colors-white, blue, yellow, orange, and red. The color indicates the star’s temperature in its photosphere, the layer where the star emits most of its visible light.

Detailed explanation-4: -The fact that stars come in different colours is not a mere curiosity. The colour provides a fundamental piece of data in stellar astrophysics-the surface temperature of the star. The hottest stars are blue and the coldest are red, contrary to the use of colours in art and in our daily experience.
