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 3.8° across: 7.1 times the Sun as we see it from Earth.

In the sky

A telescope is needed to see it: its apparent magnitude is 12.45. Visible from the whole Southern Hemisphere and north to latitude 9° N. South of latitude 9° S it never sets.

Light's journey

The light you see tonight set out around the year 1270. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 13 million years.
