In the sky
Visible to the naked eye under a dark sky (apparent magnitude 5.09). Visible from the whole Southern Hemisphere and north to latitude 67° N. South of latitude 67° 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 1153. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 15 million years.
The Sun seen from there
From a planet around 12 Pup, the Sun would look like a star of magnitude 11.97, in the direction where our sky has the constellation Vulpecula. It would be invisible to the naked eye.
