Through a telescope from Earth
Light's journey
The light you see tonight set out 8,077 years ago. At that time the first farming villages were being founded; there was no writing yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 143 million years.
The Sun seen from there
From a planet around HIP 33754, the Sun would look like a star of magnitude 16.80, in the direction where our sky has the constellation Aquila. It would be invisible to the naked eye.
