Habitable zone
Beyond the habitable zone: it receives only %4.6 of the light the Earth does, a frozen world.
Its star in the sky
In the planet's sky its star is a disc 0.15° across: 0.28 times the Sun as we see it from Earth.
In the sky
A telescope is needed to see it: its apparent magnitude is 19.86. Visible from the whole Southern Hemisphere and north to latitude 27° N. South of latitude 27° S it never sets. It stands highest at midnight in February, the best time to observe it.
Light's journey
The light you see tonight set out 14 thousand years ago. At that time Homo sapiens was spreading out of Africa; there was no farming yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 251 million years.
