In the sky
Visible to the naked eye under a dark sky (apparent magnitude 5.69). Visible from the whole Northern Hemisphere and south to latitude 60° S. North of latitude 60° 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 933 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 52 million years.
The Sun seen from there
From a planet around HIP 25492, the Sun would look like a star of magnitude 14.62, in the direction where our sky has the constellation Scorpius. It would be invisible to the naked eye.
