In the sky
A telescope is needed to see it: its apparent magnitude is 10.18. Visible from the whole Southern Hemisphere and north to latitude 76° N. South of latitude 76° 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 1010 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 54 million years.
The Sun seen from there
From a planet around BD-13 2130, the Sun would look like a star of magnitude 14.67, in the direction where our sky has the constellation Aquila. It would be invisible to the naked eye.
