In the sky
A telescope is needed to see it: its apparent magnitude is 10.90. Visible from the whole Northern Hemisphere and south to latitude 89° S. It stands highest at midnight in November, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around 1452 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 62 million years.
The Sun seen from there
From a planet around GJ 3211, the Sun would look like a star of magnitude 14.97, in the direction where our sky has the constellation Serpens. 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.
