In the sky
Visible to the naked eye under a dark sky (apparent magnitude 5.15). Visible from the whole Southern Hemisphere and north to latitude 49° N. South of latitude 49° S it never sets. It stands highest at midnight in May, the best time to observe it.

Light's journey
The light you see tonight set out 11 thousand 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 195 million years.
The Sun seen from there
From a planet around HIP 74707, the Sun would look like a star of magnitude 17.47, in the direction where our sky has the constellation Perseus. It would be invisible to the naked eye.
Position, brightness and colour from the HYG / AT-HYG catalogue; temperature, luminosity, radius and mass are approximate values computed from these observations.
