Visible to the naked eye under a dark sky (apparent magnitude 6.26). Visible from the whole Northern Hemisphere and south to latitude 83° S. It stands highest at midnight in December, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out 4,568 years ago. At that time the first farming villages were being founded; there was no writing yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 81 million years.
The Sun seen from there
From a planet around HIP 30541, the Sun would look like a star of magnitude 15.56, in the direction where our sky has the constellation Scutum. It would be invisible to the naked eye.
