In the sky
Visible to the naked eye under a dark sky (apparent magnitude 6.27). Visible from the whole Southern Hemisphere and north to latitude 23° N. South of latitude 23° S it never sets. It stands highest at midnight in February, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1292. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 13 million years.
The Sun seen from there
From a planet around HIP 46737, the Sun would look like a star of magnitude 11.59, in the direction where our sky has the constellation Cepheus. It would be invisible to the naked eye.
