In the sky
A telescope is needed to see it: its apparent magnitude is 11.99. Visible from the whole Northern Hemisphere and south to latitude 34° S. North of latitude 34° N it never sets. It stands highest at midnight in July, the best time to observe it.

Light's journey
The light you see tonight set out around the year 471. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 28 million years.
The Sun seen from there
From a planet around WASP-194, the Sun would look like a star of magnitude 13.22, in the direction where our sky has the constellation Carina. It would be invisible to the naked eye.
