In the sky
Visible to the naked eye under a dark sky (apparent magnitude 5.23). Visible from the whole Northern Hemisphere and south to latitude 62° S. North of latitude 62° N it never sets. It stands highest at midnight in February, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1441. 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 ρ² Cnc, the Sun would look like a star of magnitude 11.10, in the direction where our sky has the constellation Microscopium. It would be invisible to the naked eye.
