DeutschList of nearest hypergiants
This is a list of the nearest hypergiant stars to Earth, located at a distance of up to 10,000 light-years (3,100 parsecs) from Earth.
While hypergiants are typically defined as stars with luminosity classes 0, Ia-0 or Ia+, other definitions exist, such as those based on stellar evolution. Therefore, stars with other luminosity classes can sometimes be considered hypergiants.
