In the sky
Visible to the naked eye under a dark sky (apparent magnitude 6.14). Visible from the whole Southern Hemisphere and north to latitude 29° N. South of latitude 29° S it never sets. It stands highest at midnight in May, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around 950 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 53 million years.
The Sun seen from there
From a planet around HIP 77927, the Sun would look like a star of magnitude 14.63, in the direction where our sky has the constellation Camelopardalis. It would be invisible to the naked eye.
