A telescope is needed to see it: its apparent magnitude is 10.80. Visible from the whole Northern Hemisphere and south to latitude 11° S. North of latitude 11° N it never sets.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 2009. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 304 thousand years.
The Sun seen from there
From a planet around Gl 445, the Sun would look like a star of magnitude 3.43, in the direction where our sky has the constellation Octans. It would be visible to the naked eye.
