Visible to the naked eye under a dark sky (apparent magnitude 5.80). Visible from the whole Northern Hemisphere and south to latitude 15° S. North of latitude 15° N it never sets.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1363. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 12 million years.
The Sun seen from there
From a planet around HIP 111660, the Sun would look like a star of magnitude 11.37, in the direction where our sky has the constellation Carina. 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.
