List of most massive stars

This is an incomplete list of the most massive stars discovered.

Although O type stars are considered the most massive stars in the main sequence, evolved stars such as wolf-rayet stars and luminous blue variables can be just as massive or even more massive than them. 

These stars are extremely luminous, observing them are very difficult because they are extremely rare and most of them are located in young star-forming regions very far away. Stars at larger distances can be hard to observe, the large amount of gas surrounding them can make them much harder to even be detected.

The stars in the list below are at least 100 solar masses.
