In the sky
A telescope is needed to see it: its apparent magnitude is 9.10. Visible from the whole Southern Hemisphere and north to latitude 62° N. South of latitude 62° S it never sets. It stands highest at midnight in October, the best time to observe it.

Light's journey
The light you see tonight set out around the year 1880. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 2.6 million years.
The Sun seen from there
From a planet around HD 15337, the Sun would look like a star of magnitude 8.09, in the direction where our sky has the constellation Boötes. It would be invisible to the naked eye.
