In the sky
Visible to the naked eye under a dark sky (apparent magnitude 6.24). Visible from the whole Southern Hemisphere and north to latitude 71° N. South of latitude 71° S it never sets. 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 10 thousand 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 183 million years.
The Sun seen from there
From a planet around HIP 35975, the Sun would look like a star of magnitude 17.33, in the direction where our sky has the constellation Sagitta. It would be invisible to the naked eye.
