Light's journey
The light you see tonight set out around the year 379. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 29 million years.
The Sun seen from there
From a planet around TCP J05074264+2447555, the Sun would look like a star of magnitude 13.35, in the direction where our sky has the constellation Ophiuchus. It would be invisible to the naked eye.
