Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1996. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 530 thousand years.
The Sun seen from there
From a planet around Gl 283B, the Sun would look like a star of magnitude 4.64, in the direction where our sky has the constellation Sagitta. It would be visible to the naked eye.
