In the sky
Too faint for the naked eye (magnitude 6.60); binoculars will find it. Visible from the whole Northern Hemisphere and south to latitude 41° S. North of latitude 41° 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 2010. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 282 thousand years.
The Sun seen from there
From a planet around Gl 380, the Sun would look like a star of magnitude 3.27, in the direction where our sky has the constellation Grus. It would be visible to the naked eye.
