Too faint for the naked eye (magnitude 8.88); binoculars will find it. Visible from the whole Northern Hemisphere and south to latitude 13° S. North of latitude 13° N it never sets.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1971. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 974 thousand years.
The Sun seen from there
From a planet around Gl 786, the Sun would look like a star of magnitude 5.96, in the direction where our sky has the constellation Chamaeleon. It would be visible to the naked eye.
