In the sky
A telescope is needed to see it: its apparent magnitude is 23.36. Visible from the whole Northern Hemisphere and south to latitude 61° S. North of latitude 61° N it never sets. It stands highest at midnight in June, the best time to observe it.

Light's journey
The light you see tonight set out around the year 1445. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 10 million years.
The Sun seen from there
From a planet around SDSS J165103.66+292248.0, the Sun would look like a star of magnitude 11.08, in the direction where our sky has the constellation Caelum. It would be invisible to the naked eye.
