Habitable zone
Inside the inner edge of the habitable zone: it receives 2.11 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 2.5° across: 4.6 times the Sun as we see it from Earth.
In the sky
A telescope is needed to see it: its apparent magnitude is 13.50. Visible from the whole Southern Hemisphere and north to latitude 43° N. South of latitude 43° S it never sets. It stands highest at midnight in February, the best time to observe it.
Light's journey
The light you see tonight set out around the year 1985. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 730 thousand years.
