Habitable zone
Inside the inner edge of the habitable zone: it receives 71.3 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 6.9° 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 15.54. Visible from the whole Northern Hemisphere and south to latitude 41° S. North of latitude 41° N it never sets. It stands highest at midnight in July, the best time to observe it.
Light's journey
The light you see tonight set out around 6 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 36 million years.
