Habitable zone

Inside the inner edge of the habitable zone: it receives 33.5 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 4.5° across: 8.5 times the Sun as we see it from Earth.

In the sky

Visible to the naked eye under a dark sky (apparent magnitude 3.70). Visible from the whole Northern Hemisphere and south to latitude 87° S. It stands highest at midnight in September, the best time to observe it.

Light's journey

The light you see tonight set out around the year 1891. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 2.4 million years.
