Habitable zone
Inside the inner edge of the habitable zone: it receives 494 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 12° across: 22 times the Sun as we see it from Earth.
In the sky
A telescope is needed to see it: its apparent magnitude is 14.97. Visible from the whole Northern Hemisphere and south to latitude 85° S. It stands highest at midnight in March, the best time to observe it.
Light's journey
The light you see tonight set out around the year 142. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 33 million years.
