Too faint for the naked eye (magnitude 7.65); binoculars will find it. Visible from the whole Southern Hemisphere and north to latitude 87° N. 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 1984. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 748 thousand years.
The Sun seen from there
From a planet around Gl 204, the Sun would look like a star of magnitude 5.39, in the direction where our sky has the constellation Ophiuchus. It would be visible to the naked eye.
