Light's journey
The light you see tonight set out around 1 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 36 million years.
The Sun seen from there
From a planet around HIP 69778, the Sun would look like a star of magnitude 13.80, in the direction where our sky has the constellation Cepheus. It would be invisible to the naked eye.
Position, brightness and colour from the HYG / AT-HYG catalogue; temperature, luminosity, radius and mass are approximate values computed from these observations.
