In the sky
Too faint for the naked eye (magnitude 8.32); binoculars will find it. Visible from the whole Northern Hemisphere and south to latitude 1° S. North of latitude 1° N it never sets.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1050. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 17 million years.
The Sun seen from there
From a planet around Gl 654.4, the Sun would look like a star of magnitude 12.21, in the direction where our sky has the constellation Octans. It would be invisible to the naked eye.
Position, brightness and colour from the HYG / AT-HYG catalogue; temperature, luminosity, radius and mass are approximate values computed from these observations.
