In the sky
Visible to the naked eye under a dark sky (apparent magnitude 6.25). Visible from the whole Southern Hemisphere and north to latitude 25° N. South of latitude 25° S it never sets. It stands highest at midnight in October, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1065. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 17 million years.
The Sun seen from there
From a planet around HIP 4879, the Sun would look like a star of magnitude 12.18, in the direction where our sky has the constellation Draco. It would be invisible to the naked eye.
