Light's journey
The light you see tonight set out around 56 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 37 million years.
The Sun seen from there
From a planet around TYC 0434-04538-1, the Sun would look like a star of magnitude 13.85, in the direction where our sky has the constellation Orion. It would be invisible to the naked eye.
