A blue giant (or Blue main sequence) is a very hot star. The Milky Way is estimated to have anywhere from 100 billion to 400 billion stars, but the Andromeda Galaxy boasts around one trillion stars. Due to the very high fuel consumption, blue giants have a very short lifespan (less than a million years in some cases, up to a billion in slightly cooler blue stars). - Stars are several times bigger than planets, however, some stars, such as neutron stars, are several times smaller than planets. However, astronomers measure temperatures in Kelvin (K) and 58F is roughly 288K. At the end of their helium burning phase, they will have lost most of their outer envelope, revealing the blue core. As you can see from the picture below, the giant stars tend to be blue or red. Nonetheless, with minimum temperatures of 10,000K, these stars are hot enough to emit blue light, which places them in the O, B, and sometimes early A spectral classes. Red giants are average stars, like our sun, that are running out of hydrogen to burn. Most stars you see in the night sky are actually two star systems, or binary star systems.
