Quote from: Andreas

Eta Carinae is a massive star. The most massive known. It has an estimated mass of  100-120 suns.

Recent observations confirmed the Brazilian astronomer's Augusto Daminelli model that proposed that Eta Carinae would be a double star, and no a single star, with apparent total mass among 100 - 120 times the mass of our Sun.

Due to its duplicity Eta Carinae shows spectroscopics eclipses every 5,52 years, what was confirmed by observations done in 2003 and 2008.

Like this Eta Carinae actually would be two stars with masses of 80 and 30 solar masses.

Note: a group of brasilian amateur astronomers develop an homemade spectrograph and can register the spectroscopic eclipse of Eta CArinae in 2003. The data collected by this amteur astronomers are used in the final papaer of the confirmation of the duplicity of the Eta Carinae:

ha ha ha no. It seems you know nothing about stars at all. VV Cephei has only 24-40 times the mass of the sun.
Canis Majoranis is only 30-40 times the mass of sun. Even put together they donīt have the mass of Eta Carinae.

VV Cephei and Canis Majoranis are just bloated.

The more massive star in our galaxy is a star in NGC 3603.

It's a star with 116 solar masses orbited by a companion with 89 solar masses .

No.. The largest is... THE PISTOL STAR! (mass)
It have 200 solar masses!

Apod Said that 116 + 84 = 200

It's a binary star system..

Is the Pistol Star Binary? Do they not call Binaries Stars?
