Light's journey

The light you see tonight set out around the year 162. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 33 million years.

The Sun seen from there

From a planet around HIP 43811, the Sun would look like a star of magnitude 13.61, in the direction where our sky has the constellation Capricornus. It would be invisible to the naked eye.
