In the sky
Visible to the naked eye under a dark sky (apparent magnitude 6.17). Visible from the whole Northern Hemisphere and south to latitude 79° S. North of latitude 79° N it never sets. It stands highest at midnight in December, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around 156 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 39 million years.
The Sun seen from there
From a planet around HIP 31066, the Sun would look like a star of magnitude 13.96, in the direction where our sky has the constellation Scutum. It would be invisible to the naked eye.
