Too faint for the naked eye (magnitude 6.88); binoculars will find it. Visible from the whole Northern Hemisphere and south to latitude 9° S. North of latitude 9° N it never sets.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1962. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 1.1 million years.
The Sun seen from there
From a planet around GJ 3859, the Sun would look like a star of magnitude 6.30, in the direction where our sky has the constellation Hydrus. It would be visible to the naked eye.
