In the sky
A telescope is needed to see it: its apparent magnitude is 14.28. Visible from the whole Northern Hemisphere and south to latitude 48° S. North of latitude 48° 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 9 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 36 million years.
The Sun seen from there
From a planet around Kepler-1227, the Sun would look like a star of magnitude 13.80, in the direction where our sky has the constellation Puppis. It would be invisible to the naked eye.
