Habitable zone
Inside the inner edge of the habitable zone: it receives 583 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 14° across: 26 times the Sun as we see it from Earth.
In the sky
A telescope is needed to see it: its apparent magnitude is 14.17. Visible from the whole Northern Hemisphere and south to latitude 51° S. North of latitude 51° 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 228 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 40 million years.
