Through a telescope from Earth
Light's journey
The light you see tonight set out around 21 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 36 million years.
The Sun seen from there
From a planet around HIP 85889, the Sun would look like a star of magnitude 13.82, in the direction where our sky has the constellation Auriga. It would be invisible to the naked eye.
