In the sky
Visible to the naked eye under a dark sky (apparent magnitude 5.48). Visible from the whole Northern Hemisphere and south to latitude 14° S. North of latitude 14° N it never sets.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1446. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 10 million years.
The Sun seen from there
From a planet around 19 UMi, the Sun would look like a star of magnitude 11.08, in the direction where our sky has the constellation Mensa. 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.
