Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 2011. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 263 thousand years.
The Sun seen from there
From a planet around GJ 674, the Sun would look like a star of magnitude 3.12, in the direction where our sky has the constellation Auriga. It would be visible to the naked eye.
