In the sky

Visible to the naked eye under a dark sky (apparent magnitude 6.41). Visible from the whole Northern Hemisphere and south to latitude 71° S. North of latitude 71° N it never sets. It stands highest at midnight in January, the best time to observe it.

Light's journey

The light you see tonight set out around the year 1209. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 14 million years.

The Sun seen from there

From a planet around HIP 43427, the Sun would look like a star of magnitude 11.82, in the direction where our sky has the constellation Capricornus. It would be invisible to the naked eye.
