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 18.10. Visible from the whole Southern Hemisphere and north to latitude 77° N. South of latitude 77° S it never sets. It stands highest at midnight in April, the best time to observe it.
Light's journey
The light you see tonight set out around the year 1985. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 735 thousand years.
