In the sky
Visible to the naked eye under a dark sky (apparent magnitude 4.66). Visible from the whole Northern Hemisphere and south to latitude 69° S. North of latitude 69° N it never sets. It stands highest at midnight in October, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1621. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 7.2 million years.
The Sun seen from there
From a planet around χ Psc, the Sun would look like a star of magnitude 10.30, in the direction where our sky has the constellation Virgo. 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.
