In the sky
Too faint for the naked eye (magnitude 7.83); binoculars will find it. Visible from the whole Southern Hemisphere and north to latitude 60° N. South of latitude 60° S it never sets. It stands highest at midnight in August, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1983. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 768 thousand years.
The Sun seen from there
From a planet around Gl 868, the Sun would look like a star of magnitude 5.45, in the direction where our sky has the constellation Leo Minor. It would be visible to the naked eye.
