Llista d'estrelles más grandes conocíes

La siguiente ye una llista de les estrelles más grandes conocíes hasta'l momentu, según los estudios realizaos polos astrónomos; los tamaños tán espresaos radios solares ( ${\displaystyle r_{\odot }}$ ). L'orde exactu d'esta llista nun ye definitivu nin completu. Amás, hai qu'apuntar lo siguiente:

• Les componentes de delles estrelles dobles son trataes individualmente, ente que n'otres ocasiones da información combinada.
• Hai variaciones estadístiques según el criteriu de determinación del tamañu.
• El diámetru del Sol ye d'aproximao 1 392 000 km (1,392 × 10⁹ m).

Comparanza relativa ente los planetes del Sistema Solar con delles estrelles.

Hai que tener en cuenta que non siempres les estrelles más grandes son bien masives, nin viceversa. R136a1 ye un exemplu, yá que ye la estrella más masiva (ye una hiperxigante), pero'l so radiu ye de 35,4 radios solares.
