Habitable zone
At the edge of the habitable zone (within the optimistic limits): liquid water would be possible only with a favourable atmosphere.
Its star in the sky
In the planet's sky its star is a disc 0.57° across: 1.1 times the Sun as we see it from Earth.
In the sky
A telescope is needed to see it: its apparent magnitude is 15.09. Visible from the whole Northern Hemisphere and south to latitude 45° S. North of latitude 45° 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 5,874 years ago. At that time the first farming villages were being founded; there was no writing yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 104 million years.
