In the sky
A telescope is needed to see it: its apparent magnitude is 13.50. Visible from the whole Southern Hemisphere and north to latitude 69° N. South of latitude 69° S it never sets. It stands highest at midnight in December, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1959. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 1.2 million years.
The Sun seen from there
From a planet around Gl 199B, the Sun would look like a star of magnitude 6.38, in the direction where our sky has the constellation Hercules. It would be visible to the naked eye.
