In the sky
Visible to the naked eye under a dark sky (apparent magnitude 6.22). Visible from the whole Southern Hemisphere and north to latitude 69° N. South of latitude 69° S it never sets. It stands highest at midnight in June, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out 4,224 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 75 million years.
The Sun seen from there
From a planet around HIP 88760, the Sun would look like a star of magnitude 15.39, in the direction where our sky has the constellation Orion. It would be invisible to the naked eye.
