Habitable zone
Inside the inner edge of the habitable zone: it receives 20.1 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 2.6° across: 4.9 times the Sun as we see it from Earth.
In the sky
Too faint for the naked eye (magnitude 8.00); binoculars will find it. Visible from the whole Northern Hemisphere and south to latitude 34° S. North of latitude 34° N it never sets. It stands highest at midnight in June, the best time to observe it.
Light's journey
The light you see tonight set out around the year 1805. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 3.9 million years.
