In the sky
Visible to the naked eye under a dark sky (apparent magnitude 4.82). Visible from the whole Southern Hemisphere and north to latitude 75° N. South of latitude 75° 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 384 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 43 million years.
The Sun seen from there
From a planet around HIP 36773, the Sun would look like a star of magnitude 14.17, in the direction where our sky has the constellation Aquila. It would be invisible to the naked eye.
