A supergiant star, in stellar classification, is a type of star of great mass and considerable brightness and size.

Supergiant stars are among the types of stars massive enough to end their lives as supernovae, with a massive gravitational collapse and explosion that ejects large amounts of gas and solid matter with a considerable amount of energy, sometimes leaving a remnant of a neutron star or black hole within a nebula of ejected stellar mass.

Notable supergiant starsEdit

Unnamed supergiant starsEdit

In a distant corner of the galaxy, an unnamed supergiant star went supernova around the year 2230, leaving a neutron star remnant. At roughly the same time, Spock was born many light years distant, on the planet Vulcan. (TOS novelization: Star Trek)
