Through a telescope from Earth
Light's journey
The light you see tonight set out around 523 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 45 million years.
The Sun seen from there
From a planet around HIP 97454, the Sun would look like a star of magnitude 14.29, in the direction where our sky has the constellation Monoceros. It would be invisible to the naked eye.
