Habitable zone
Inside the inner edge of the habitable zone: it receives 39.2 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 10° across: 19 times the Sun as we see it from Earth.
In the sky
A telescope is needed to see it: its apparent magnitude is 11.39. Visible from the whole Northern Hemisphere and south to latitude 80° S. It stands highest at midnight in April, the best time to observe it.
Light's journey
The light you see tonight set out around the year 2000. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 467 thousand years.
