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 elements are in Eta Carinae?
Eta Carinae is a massive binary star system located in the Carina constellation. It consists of two massive stars, with the primary star being a blue hypergiant and the companion likely a massive hot star. These stars are surrounded by a dense nebula of gas and dust.
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.
How far away is Eta from earth?
Eta Carinae is approximately 7,500 light-years away from Earth. This massive star system is located in the Carina constellation and is known for its extreme brightness and variability. Its significant distance makes it one of the more notable objects in our galaxy, often studied for its unique characteristics.
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.
What type of star is Eta Carinae?
Eta Carinae is a massive and highly unstable star known as a Luminous Blue Variable (LBV). It is one of the most massive and brightest stars known in the Milky Way galaxy, and it is located in the Carina constellation.
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.
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.
Is Eta Carinae a nebula still?
Yes it is and will be so for quite a while.
Is pistol star bigger than eta carinae?
Yes, Pistol Star is larger than Eta Carinae. Pistol Star is one of the most massive stars known, with an estimated radius about 100 times that of the Sun, while Eta Carinae is a binary star system with its most massive component having a radius roughly 90 times that of the Sun. Additionally, Pistol Star is classified as a Wolf-Rayet star, which contributes to its larger size compared to the Eta Carinae system.
What is the temperature of the eta carinae?
Eta Carinae is a massive binary star system, not a single star, so it does not have a single temperature. However, the primary star in the system has a surface temperature of approximately 25,000 Kelvin.
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 elements are in Eta Carinae?
Eta Carinae is a massive binary star system located in the Carina constellation. It consists of two massive stars, with the primary star being a blue hypergiant and the companion likely a massive hot star. These stars are surrounded by a dense nebula of gas and dust.
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!
