In the sky
Visible to the naked eye under a dark sky (apparent magnitude 5.04). Visible from the whole Southern Hemisphere and north to latitude 45° N. South of latitude 45° S it never sets. It stands highest at midnight in January, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1950. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 1.4 million years.
The Sun seen from there
From a planet around Gl 284, the Sun would look like a star of magnitude 6.67, in the direction where our sky has the constellation Cygnus. It would be invisible to the naked eye.
