Light's journey
The light you see tonight set out around the year 2009. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 295 thousand years.
The Sun seen from there
From a planet around Gl 702B, the Sun would look like a star of magnitude 3.37, in the direction where our sky has the constellation Orion. It would be visible to the naked eye.
