The concerns about nearby supernovas mostly focus on supernovae within 50 light-years of the Earth.
- Eta Carinae, at 8000 light-years is 160 times farther away.
- Because intensity drops as the square of distance, Eta Carinae will be around 25,000 times dimmer than a "risky" supernova at 50 light-years.
