Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 998. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 18 million years.
The Sun seen from there
From a planet around HIP 74716, the Sun would look like a star of magnitude 12.32, in the direction where our sky has the constellation Perseus. It would be invisible to the naked eye.
