A world with a story

More than a beautiful planet.

Host star: Kepler-16 A + B
Star type: Binary stellar system
Planet radius: 0.754 × Jupiter
Planet mass: 0.333 × Jupiter
Orbital period: c. 228.8 days
Orbital distance: 0.7048 AU
Discovery: 2011 · Transit

Values are rounded from published catalogue measurements. Sky coordinates identify the host system, not a resolved planetary surface.

A planet with two suns

Kepler-16 b is circumbinary: its orbit surrounds two stars together. It is a gas giant rather than a rocky landscape for watching sunsets from. The binary system is its defining astronomical feature.

Where is Kepler-16 b?

The system lies in Cygnus, approximately 245 light-years away. Its stellar pair is identified as Kepler-16 A and B. The planet’s orbit lasts about 228.8 days, much longer than those of our extremely close-orbiting hot giants.

A cold giant, despite the double daylight

Two stars do not automatically mean a hotter planet. Kepler-16 b is a relatively cold, Saturn-sized giant. Its measured mass is about a third of Jupiter’s, while its radius is roughly three quarters of Jupiter’s.

What might double illumination look like?

The artwork shows two separate stellar sources illuminating an enormous gas giant. Their placement, apparent brightness and cloud patterns are a chosen viewing interpretation. It is an astronomy-led reconstruction, with no borrowed fictional planets or landscapes.

How was it discovered?

Kepler observations revealed planet transits and stellar eclipses. The changing geometry of a binary system makes the light pattern especially interesting. The catalogue records its transit discovery in 2011.

Twice the light, entirely unofficial

A personalised name appears alongside Kepler-16 b on the artwork and commemorative certificate. You are giving a meaningful astronomy gift, not naming a star system officially. Two suns, fortunately, require no extra personalisation fee.
