why is the hotest star blue in colour and coolest star red in colour

Answers

Answered by Sanjana5428

The colour of a star is primarily a function of its effective temperature. ... Hot stars appear blue because most energy is emitted in the bluer parts of the spectrum. There is little emission in the blue parts of the spectrum for cool stars - they appear red.
