In the sky
Visible to the naked eye under a dark sky (apparent magnitude 6.48). Visible from the whole Northern Hemisphere and south to latitude 80° S. North of latitude 80° N it never sets. It stands highest at midnight in January, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1460. 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 34 Cnc, the Sun would look like a star of magnitude 11.03, in the direction where our sky has the constellation Capricornus. It would be invisible to the naked eye.
