If Sirius went supernova what would happen to us?

Question

The supernova of 1054 was bright enough to be seen in daylight but was 5000 light years away. Sirius is only 9 light years away, were can I hide!

Answer 1

I dont know but i'm guessing it would be pretty sirius !

Answer 2

It would be bad...

I'm copying this out of wikipedia because its a bit hard to find in the article:

A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly fewer than 100 light-years away) to have noticeable effects on its biosphere. Gamma rays are responsible for most of the adverse effects a supernova can have on a living terrestrial planet. In Earth's case, gamma rays induce a chemical reaction in the upper atmosphere, converting ozone into nitrous oxide, depleting the ozone layer enough to expose the surface to harmful solar and cosmic radiation. The gamma ray burst from a nearby supernova explosion has been proposed as the cause of the Ordovician extinction, which resulted in the death of nearly 60% of the oceanic life on Earth. [31]

Speculation as to the effects of a nearby supernova on Earth often focuses on large stars, such as Betelgeuse, a red supergiant four hundred and twenty-seven light years from Earth which is a type II supernova candidate. Several prominent stars within a few light centuries from Sol are candidates for becoming supernovae in as little as a millenium. Though spectacular, these "predictable" supernovae are thought to have little potential to affect Earth. Type Ia supernovae, though, are thought to be potentially the most dangerous if they occur close enough to the Earth. Because Type Ia supernovae arise from dim, common white dwarf stars, it is likely that a supernova that could affect the Earth will occur unpredictably and take place in a star system that is not well studied. One theory suggests that a Type Ia supernova would have to be closer than a thousand parsecs (3300 light years) to affect the Earth.[32]

Recent estimates predict that a Type II supernova would have to be closer than eight parsecs (twenty-six light years) to destroy half of the Earth's ozone layer.[33] Such estimates are mostly concerned with atmospheric modeling and considered only the known radiation flux from SN 1987A, a Type II supernova in the Large Magellanic Cloud. Estimates of the rate of supernova occurrence within 10 parsecs of the Earth vary from once every 100 million years [34] to once every one to ten billion years.[35]

In 1996, astronomers at the University of Illinois at Urbana-Champaign theorized that traces of past supernovae might be detectable on Earth in the form of metal isotope signatures in rock strata. Subsequently, iron-60 enrichment has been reported in deep-sea rock of the Pacific Ocean by researchers from the Technical University of Munich.[36][37][38

Answer 3

No Sirius? No more Howard Stern?

Answer 4

Nine light years distant is still far enough of a buffer between us.

Answer 5

Stock up on the sunblock.

Answer 6

Nothing will happen.

Answer 7

you can hide under your bed. nothing happen to us.....

Answer 8

I don't know

Answer 9

nothing, why do you ask???
