In the sky
Visible to the naked eye under a dark sky (apparent magnitude 6.05). Visible from the whole Southern Hemisphere and north to latitude 47° N. South of latitude 47° 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 172. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 33 million years.
The Sun seen from there
From a planet around HIP 38370, the Sun would look like a star of magnitude 13.60, in the direction where our sky has the constellation Cygnus. It would be invisible to the naked eye.
