Habitable zone
Inside the inner edge of the habitable zone: it receives 20.5 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 7.1° across: 13 times the Sun as we see it from Earth.
In the sky
A telescope is needed to see it: its apparent magnitude is 13.12. Visible from the whole Northern Hemisphere and south to latitude 23° S. North of latitude 23° N 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 1974. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 926 thousand years.
