Habitable zone
Inside the inner edge of the habitable zone: it receives 544 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 16° across: 30 times the Sun as we see it from Earth.
In the sky
A telescope is needed to see it: its apparent magnitude is 9.97. Visible from the whole Northern Hemisphere and south to latitude 32° S. North of latitude 32° N it never sets. It stands highest at midnight in October, the best time to observe it.
Light's journey
The light you see tonight set out around the year 469. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 28 million years.
