Habitable zone
Beyond the habitable zone: it receives only %0 of the light the Earth does, a frozen world.
In the sky
A telescope is needed to see it: its apparent magnitude is 15.54. Visible from the whole Northern Hemisphere and south to latitude 65° S. North of latitude 65° N it never sets. It stands highest at midnight in November, the best time to observe it.
Light's journey
The light you see tonight set out around the year 1591. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 7.7 million years.
