Through a telescope from Earth
Light's journey
The light you see tonight set out around 898 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 52 million years.
The Sun seen from there
From a planet around HIP 97774, the Sun would look like a star of magnitude 14.59, in the direction where our sky has the constellation Puppis. It would be invisible to the naked eye.
