A B-Type Main Sequence Star is a type of star that is larger and hotter than our Sun. These stars have surface temperatures ranging from about 10,000 to 30,000 degrees Celsius. They are typically blue or blue-white in color and are very luminous, shining with a brightness that can be hundreds to thousands of times greater than that of the Sun. B-type stars are relatively short-lived, with lifespans of only a few million years. They burn their nuclear fuel quickly, primarily through the process of hydrogen fusion. After exhausting their hydrogen, they evolve into different types of stars, such as supernovae or neutron stars.
