In the sky
Visible to the naked eye under a dark sky (apparent magnitude 5.69). Visible from the whole Southern Hemisphere and north to latitude 65° N. South of latitude 65° S it never sets. It stands highest at midnight in January, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around 49 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 37 million years.
The Sun seen from there
From a planet around HIP 34579, the Sun would look like a star of magnitude 13.85, in the direction where our sky has the constellation Vulpecula. It would be invisible to the naked eye.
