In the sky
Too faint for the naked eye (magnitude 6.78); binoculars will find it. Visible from the whole Northern Hemisphere and south to latitude 42° S. North of latitude 42° 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 991. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 18 million years.
The Sun seen from there
From a planet around 88 Her, the Sun would look like a star of magnitude 12.34, in the direction where our sky has the constellation Pictor. It would be invisible to the naked eye.
