In the sky
Visible to the naked eye under a dark sky (apparent magnitude 4.89). Visible from the whole Southern Hemisphere and north to latitude 36° N. South of latitude 36° S it never sets. It stands highest at midnight in February, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1954. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 1.3 million years.
The Sun seen from there
From a planet around Gl 397.2, the Sun would look like a star of magnitude 6.55, in the direction where our sky has the constellation Lacerta. It would be invisible to the naked eye.
