In the sky
A telescope is needed to see it: its apparent magnitude is 13.85. Visible from the whole Northern Hemisphere and south to latitude 37° S. North of latitude 37° N it never sets. It stands highest at midnight in February, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1992. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 594 thousand years.
The Sun seen from there
From a planet around Gl 339.1, the Sun would look like a star of magnitude 4.89, in the direction where our sky has the constellation Indus. It would be visible to the naked eye.
