Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 801. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 22 million years.
The Sun seen from there
From a planet around WASP-103, the Sun would look like a star of magnitude 12.70, in the direction where our sky has the constellation Eridanus. It would be invisible to the naked eye.
