Light's journey
The light you see tonight set out around the year 867. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 21 million years.
The Sun seen from there
From a planet around HIP 30660, the Sun would look like a star of magnitude 12.58, in the direction where our sky has the constellation Serpens. 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.
