An excellent question, but without a good answer. Eta Carina is one of the most massive stars that we know of (yet), with a mass upwards of 100 solar masses.
Very massive stars live fast and die young, so we expect it to become a supernova "relatively soon", but "relatively soon" to an astronomer means "Between 10,000 years and 1,000,000 years from now". There is no indication that this event is going to happen within our lifetimes, although at 8,000 light years away, it's possible that we just didn't notice. At that mass, its ultimate fate is most probably to become a black hole.

How big is Eta Carinae?
Eta Carinae is actually a star system comprising of at least two massive stars.Eta Carinae A: Has a diameter about 3.3 x 109Km (If replaced with the Sun it would extend to the orbit of Jupiter)Eta Carinae B: Is about half that of Eta Carinae AHowever, it is difficult to be precise as both stars are contained within the Homunculus Nebula and they are shedding material at around the mass of the Earth each day.
What is the temp of high mass star?
Eta Carinae, with a mass 180 times that of the sun has a surface temperature of around 40,000 K. It is the hottest known star.
What is the name of the biggest star in galaxy?
'Sol' also known as the sun is the only star in our solar system and is therefore the biggest one. If you meant planets than that would be Jupiter.
Can a planet go supernova?
No, only large stars go supernova when nuclear fusion breaks down. While white dwarfs can go supernova in some instances, brown dwarfs are failed stars which are not powered by nuclear fusion.
Which star has the greatest probability of producing a supernova explosion?
There is no way of knowing which star will next go "supernova".However, closer to home, Betelgeuse is the most likely to produce a supernova - within humanities lifetime.
What type of star is Eta Carinae?
Eta Carinae is a luminous blue variable (LBV) variable star. It is at least a binary system. One day, it is expected to explode as a supernova - possibly in our lifetime.
What is the temperature of the eta carinae?
Hot!
How far is Eta Carinae?
Eta Carinae is a stellar system in the constellation Carina.It is approximately 7,500 -> 8,000 light years from us.
What is the mass of eta carinae?
Eta Carinae is a stellar system in the constellation Carina.It has a mass of about 100 -> 150 Suns. [See related question]

The biggest star in galaxy?
Eta Carinae.
What is the difference between Eta Carina and Eta Carinae?
Eta Carina is a dance band from Charlotte, North Carolina.Eta Carinae is a star system in the Carina constellation about 8,000 light years from our sun.
Is Eta Carinae a nebula still?
Yes it is and will be so for quite a while.
What is the peak radiation for the hottest stars?
Eta Carinae is one of the hottest known stars, with a surface temperature of approximately 38000 Kelvins. According to Wien's displacement law, the peak radiation of Eta Carinae is 76 nanometers, which is far into the ultraviolet spectrum.
What is the hottest supergiant?
Probably Eta Carinae with a surface temperature of 36,000 - 40,000 degrees Kelvin.
How big are the biggest stars compared to the sun?
Probably Eta Carinae, with a radius 400 times the size of our sun.
What age are stars before they explode?
It depends on the initial mass of the star - i.e., how much actual material it contains. The more massive a star is, the shorter its 'life'. Most stars average out at roughly the mass of the Sun (certainly within a fairly narrow range either side of it at least) and the lifetime for such stars is therefore about the same as the Sun's - about 10 billion years. Really massive stars like eta Carinae will run through their nuclear reactions at a much faster rate and so will only last for a few million years. Eta Carinae could go supernova any day now!
