In the sky
Visible to the naked eye under a dark sky (apparent magnitude 6.26). Visible from the whole Southern Hemisphere and north to latitude 52° N. South of latitude 52° 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 819 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 50 million years.
The Sun seen from there
From a planet around HIP 86246, the Sun would look like a star of magnitude 14.53, in the direction where our sky has the constellation Auriga. It would be invisible to the naked eye.
