In the sky

Visible to the naked eye under a dark sky (apparent magnitude 6.31). Visible from the whole Southern Hemisphere and north to latitude 42° N. South of latitude 42° S it never sets. It stands highest at midnight in May, the best time to observe it.

Light's journey

The light you see tonight set out around the year 1861. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 2.9 million years.

The Sun seen from there

From a planet around HIP 78117, the Sun would look like a star of magnitude 8.35, in the direction where our sky has the constellation Perseus. It would be invisible to the naked eye.
