Habitable zone
Beyond the habitable zone: it receives only %3.4 of the light the Earth does, a frozen world.
Its star in the sky
In the planet's sky its star is a disc 0.11° across: 0.2 times the Sun as we see it from Earth.
In the sky
Too faint for the naked eye (magnitude 7.34); binoculars will find it. Visible from the whole Southern Hemisphere and north to latitude 83° N. It stands highest at midnight in March, the best time to observe it.
Light's journey
The light you see tonight set out around the year 1915. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 2.0 million years.
