Habitable zone

Inside the inner edge of the habitable zone: it receives 8.2 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 1.1° across: 2.1 times the Sun as we see it from Earth.

In the sky

A telescope is needed to see it: its apparent magnitude is 14.97. Visible from the whole Northern Hemisphere and south to latitude 49° S. North of latitude 49° 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 4,332 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 77 million years.
