In the sky
Visible to the naked eye under a dark sky (apparent magnitude 6.15). Visible from the whole Southern Hemisphere and north to latitude 55° N. South of latitude 55° 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 around 1446 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 62 million years.
The Sun seen from there
From a planet around HIP 83706, the Sun would look like a star of magnitude 14.97, in the direction where our sky has the constellation Auriga. It would be invisible to the naked eye.
