Habitable zone
Beyond the habitable zone: it receives only %14 of the light the Earth does, a frozen world.
Its star in the sky
In the planet's sky its star is a disc 0.32° across: 0.61 times the Sun as we see it from Earth.
In the sky
Visible to the naked eye under a dark sky (apparent magnitude 3.29). Visible from the whole Northern Hemisphere and south to latitude 31° S. North of latitude 31° N it never sets. It stands highest at midnight in May, the best time to observe it.
Light's journey
The light you see tonight set out around the year 1924. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 1.8 million years.
