Yes there is a good possibility that Kochab is going to or has gone supernova. The Star is in the right phase and also has sufficient mass to experience a supernova.
However, this has nothing to do with myths or predictions. Nostradamis may have said "It would appear from the experience that Kochab went supernova" but how would he know? As nothing, especially information can travel faster than the speed of light, there is no way he could have known that Kochab had gone supernova without seeing the light as well.
Considering the letter was dated in 1558 and Kochab is only about 120 light years away, we should have seen the outburst in 1678!
This was also one of the way to many basic flaws in the movie 2012 supernova.
What else can I help you with?
What is the color of the star Kochab?
Kochab is an orange giant star, so it appears orange in color.
Is a star going supernova in the Orion?
There are currently no stars in the Orion constellation showing signs of going supernova. If a star in the Orion constellation were to go supernova, it would likely be visible to us on Earth given Orion's proximity.
How hot is kochab?
Beta Ursae Minoris (Kochab) is the brightest star in the bowl of the "Little Dipper" - part of the constellation Ursa Minor.It has a surface temperature of about 4,030 Kelvin.
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.
How can you use supernova in a sentence?
Heavy stars go supernova at the end of their lives.
When will a star go supernova?
Currently, there is no real way of knowing when a star will go supernova within a few thousand to million years. There are signs, that a star will go supernova based on physics and observations but WHEN is a problem. A star will "pulse" in a "last breath" prior to going supernova, but like death itself, no one really knows, when that last breath will happen. Betelgeuse, is experiencing those "last breaths" but when it will happen, or has happened, we will not know until we see the brilleint outburst from Earth.
How far away is Kochab from Earth?
From Wiki:126 ± 3 ly(38.8 ± 0.8 pc)
What are three stars associated with polaris?
Thuban, Kochab and Cynosura.
When will the sun be supernova?
Never. A star must be about 10 times the mass of the sun or more to go supernova.
Where is the star Kochab located on the little dipper?
The star Polaris is at the tip of the handle of the little dipper or Ursa Minor. Kochab is at the end of the ladle.
What type of star is kochab?
Kochab is a giant star of spectral type K4 located in the constellation Ursa Minor. It is an orange-hued star that is approximately 130 light years away from Earth.
Can we predict when the next supernova will happen?
Unfortunately not. We can tell which stars are likely to go Supernova, but our time frame is limited to hundreds if not, closer to thousands of years. Viewable supernova are rare and therefore we have not been able to study them sufficiently with modern instruments to gain an insight into their workings. As more and more supernova are observed our predictions could become better, but not for a long while.
