Habitable zone
Beyond the habitable zone: it receives only %0.1 of the light the Earth does, a frozen world.
Its star in the sky
In the planet's sky its star is a disc 0.024° across: 0.045 times the Sun as we see it from Earth.
In the sky
Visible to the naked eye under a dark sky (apparent magnitude 4.69). Visible from the whole Southern Hemisphere and north to latitude 33° N. South of latitude 33° S it never sets. It stands highest at midnight in August, the best time to observe it.
Light's journey
The light you see tonight set out around the year 2014. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 211 thousand years.
