In the sky
Too faint for the naked eye (magnitude 6.90); binoculars will find it. Visible from the whole Southern Hemisphere and north to latitude 20° N. South of latitude 20° S it never sets. It stands highest at midnight in September, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1847. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 3.2 million years.
The Sun seen from there
From a planet around GJ 4318, the Sun would look like a star of magnitude 8.52, in the direction where our sky has the constellation Ursa Major. It would be invisible to the naked eye.
