In the sky
A telescope is needed to see it: its apparent magnitude is 9.97. Visible from the whole Northern Hemisphere and south to latitude 78° S. North of latitude 78° N it never sets. It stands highest at midnight in January, the best time to observe it.
Light's journey
The light you see tonight set out around 656 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 48 million years.
