Habitable zone
Beyond the habitable zone: it receives only %9.6 of the light the Earth does, a frozen world.
Its star in the sky
In the planet's sky its star is a disc 0.25° across: 0.48 times the Sun as we see it from Earth.
In the sky
A telescope is needed to see it: its apparent magnitude is 13.07. Visible from the whole Northern Hemisphere and south to latitude 43° S. North of latitude 43° 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 1400. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 11 million years.
