Visible to the naked eye under a dark sky (apparent magnitude 5.95). Visible from the whole Northern Hemisphere and south to latitude 86° S. 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 1400. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 11 million years.
The Sun seen from there
From a planet around HIP 37478, the Sun would look like a star of magnitude 11.25, in the direction where our sky has the constellation Aquila. 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.
