How big is the star? How far away is the star? Inverse square law is our friend.
If it is Sirius, 16 light years away, then we have a problem. If it is Betelgeuse, 300 light years away, we have a spectacular light show.
It has the mass of 1 Sol.
How far away is the star?
About 93,000,000 miles on the average, call it 8 light minutes.
Inverse square law is our friend.
Sometimes...
On the bright side our Sun is a periodic micronova, with a periodicity of about 12,000 years.
On the really, really, really too bright side the last pop was about 12,000 years ago.
