Habitable zone
Inside its star's habitable zone: it receives enough light for liquid water to exist on its surface under a suitable atmosphere.
Its star in the sky
In the planet's sky its star is a disc 1.5° across: 2.9 times the Sun as we see it from Earth.
In the sky
A telescope is needed to see it: its apparent magnitude is 13.03. Visible from the whole Southern Hemisphere and north to latitude 45° N. South of latitude 45° S it never sets. It stands highest at midnight in November, the best time to observe it.
Light's journey
The light you see tonight set out around the year 2014. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 212 thousand years.
