It might be a long way out. The apparent brightness, in photons per
square degree, doesn't change with distance -- the amount of light
received by a given collector (e.g. your pupil) drops off according to the
inverse-square law, but so does the apparent area of the Sun.

Drat. You beat me to it. But continuing to the logical conclusion, the
Sun will continue to be a hazard until it's too small to resolve (1
minute of arc ??)
