Habitable zone
Beyond the habitable zone: it receives only %26 of the light the Earth does, a frozen world.
Its star in the sky
In the planet's sky its star is a disc 0.29° across: 0.55 times the Sun as we see it from Earth.
In the sky
Too faint for the naked eye (magnitude 8.52); binoculars will find it. Visible from the whole Northern Hemisphere and south to latitude 69° S. North of latitude 69° 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 1861. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 2.9 million years.
