Habitable zone
Inside the inner edge of the habitable zone: it receives 4.89 times the light the Earth does, too hot to keep liquid water on its surface.
Its star in the sky
In the planet's sky its star is a disc 1° across: 1.9 times the Sun as we see it from Earth.
In the sky
Visible to the naked eye under a dark sky (apparent magnitude 4.10). Visible from the whole Northern Hemisphere and south to latitude 49° S. North of latitude 49° N it never sets. It stands highest at midnight in October, the best time to observe it.
Light's journey
The light you see tonight set out around the year 1982. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 776 thousand years.
