Habitable zone

Inside the inner edge of the habitable zone: it receives 140 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 5.9° across: 11 times the Sun as we see it from Earth.

In the sky

A telescope is needed to see it: its apparent magnitude is 14.65. Visible from the whole Northern Hemisphere and south to latitude 40° S. North of latitude 40° 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 around 960 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 53 million years.
