How does a blue star compare to the sun?

A blue star is significantly hotter and more massive than the Sun, with surface temperatures typically exceeding 10,000 Kelvin, compared to the Sun's approximately 5,500 Kelvin. Blue stars burn their nuclear fuel much faster, leading to shorter lifespans, often only a few million years, whereas the Sun has a lifespan of about 10 billion years. Additionally, blue stars emit more light and energy, often appearing much brighter than the Sun, which is classified as a yellow dwarf.
