In the sky
Visible to the naked eye under a dark sky (apparent magnitude 5.16). Visible from the whole Northern Hemisphere and south to latitude 52° S. North of latitude 52° N it never sets. It stands highest at midnight in September, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1863. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 2.9 million years.
The Sun seen from there
From a planet around ρ And, the Sun would look like a star of magnitude 8.33, in the direction where our sky has the constellation Centaurus. It would be invisible to the naked eye.
