Habitable zone
Inside its star's habitable zone: it receives enough light for liquid water to exist on its surface under a suitable atmosphere.
Its star in the sky
In the planet's sky its star is a disc 0.37° across: 0.69 times the Sun as we see it from Earth.
In the sky
Visible to the naked eye under a dark sky (apparent magnitude 5.77). Visible from the whole Southern Hemisphere and north to latitude 84° N. 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 1941. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 1.5 million years.
