In the sky
A telescope is needed to see it: its apparent magnitude is 16.23. Visible from the whole Southern Hemisphere and north to latitude 37° N. South of latitude 37° S it never sets. It stands highest at midnight in March, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 2019. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 116 thousand years.
The Sun seen from there
From a planet around Luhman 16, the Sun would look like a star of magnitude 1.33, in the direction where our sky has the constellation Lacerta. It would be visible to the naked eye.
