Blue+Giants+2B


 * A blue giant is a star with a spectral type of O or B and are very rare and very bright.
 * It is a huge, very hot, very luminous, blue star.
 * These incredibly hot stars burn helium.
 * They have at least 18 times the mass of the sun. (Examples: Rigel and Regulus.)
 * Blue giants typically have a luminosity of 10,000 Lsun and a surface temperature of 30,000 K.
 * Blue giants are extremely luminous, reaching absolute magnitudes of -5, -6 and even higher.
 * Their surface temperature is 20,000 K or more.
 * Mintaka has a magnitude of 2.2 and is a blue giant class B0 star.
 * Distances is 800 light years away.
 * When a star has the mass of a blue giant, it can swell several times before it's final collapse.
 * When the collapse occurs the mass is to great for the electrons to stop it from further collapsing.
