In the sky
A telescope is needed to see it: its apparent magnitude is 14.09. Visible from the whole Southern Hemisphere and north to latitude 88° N. It stands highest at midnight in October, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around 1287 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 59 million years.
The Sun seen from there
From a planet around GJ 3079, the Sun would look like a star of magnitude 14.86, in the direction where our sky has the constellation Virgo. It would be invisible to the naked eye.
