Anexo:Estrellas más grandes conocidas

La siguiente es una lista de las estrellas más grandes conocidas hasta el momento, según los estudios realizados por los astrónomos; los tamaños están expresados en radios solares ( ). El orden exacto de esta lista no es definitivo ni completo. Además, hay que apuntar lo siguiente:

  • Las componentes de algunas estrellas dobles son tratadas individualmente, mientras que en otras ocasiones se da información combinada.
  • Hay variaciones estadísticas según el criterio de determinación del tamaño.
  • El diámetro del Sol es de aproximadamente 1 392 000 km (1,392 × 109 m).
Comparación relativa entre los planetas del Sistema Solar con varias estrellas.

Hay que tener en cuenta que no siempre las estrellas más grandes son muy masivas, ni viceversa. R136a1 es un ejemplo, dado que es la estrella más masiva (es una hipergigante), pero su radio es de 35,4 radios solares.
