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 0.52° across: 0.98 times the Sun as we see it from Earth.
In the sky
A telescope is needed to see it: its apparent magnitude is 9.32. Visible from the whole Northern Hemisphere and south to latitude 11° S. North of latitude 11° N it never sets.
Light's journey
The light you see tonight set out around the year 1638. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 6.9 million years.
