"At a distance of approximately 11,500 astronomical units (0.18 light
years) going out into interstellar space, the Sun fades to a magnitude
of -6.5. At around this point its light intensity will be equivalent
to just 1/300th of a full moon shining down on Earth (based on an
absolute magnitude of +4.75) which is exactly the same as my total
cosmic sky illumination figure...

Hence going outward from this point on, our Sun will no longer be the
chief source of light and the light produced by the cosmic night sky
will start to become the dominant source of illumination to any
interstellar traveller."
