Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1981. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 805 thousand years.
The Sun seen from there
From a planet around 10 Tau, the Sun would look like a star of magnitude 5.55, in the direction where our sky has the constellation Serpens. It would be visible to the naked eye.
