In the sky
Visible to the naked eye under a dark sky (apparent magnitude 6.09). Visible from the whole Northern Hemisphere and south to latitude 74° S. North of latitude 74° N it never sets. It stands highest at midnight in June, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 975. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 19 million years.
The Sun seen from there
From a planet around HIP 89023, the Sun would look like a star of magnitude 12.37, in the direction where our sky has the constellation Lepus. It would be invisible to the naked eye.
