Habitable zone
Beyond the habitable zone: it receives only %11 of the light the Earth does, a frozen world.
Its star in the sky
In the planet's sky its star is a disc 0.012° across: 0.023 times the Sun as we see it from Earth.
In the sky
Visible to the naked eye under a dark sky (apparent magnitude 3.56). Visible from the whole Southern Hemisphere and north to latitude 52° N. South of latitude 52° S 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 1450. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 10 million years.
