Light's journey
The light you see tonight set out around 415 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 43 million years.
The Sun seen from there
From a planet around TYC 1422-614-1, the Sun would look like a star of magnitude 14.20, in the direction where our sky has the constellation Aquarius. It would be invisible to the naked eye.
