In the sky
A telescope is needed to see it: its apparent magnitude is 9.95. Visible from the whole Southern Hemisphere and north to latitude 47° N. South of latitude 47° S it never sets. It stands highest at midnight in September, the best time to observe it.

Light's journey
The light you see tonight set out around the year 1875. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 2.7 million years.
The Sun seen from there
From a planet around HIP 113103, the Sun would look like a star of magnitude 8.16, in the direction where our sky has the constellation Ursa Major. It would be invisible to the naked eye.
