In the sky
Visible to the naked eye under a dark sky (apparent magnitude 5.84). 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 January, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1521. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 9.0 million years.
The Sun seen from there
From a planet around HIP 34758, the Sun would look like a star of magnitude 10.78, in the direction where our sky has the constellation Sagitta. It would be invisible to the naked eye.
