This artist's conception illustrates the Kepler-16 system (white) from an overhead view, showing its planet Kepler-16b and the eccentric orbits of the two stars it circles (labeled A and B). For reference, the orbits of our own solar system's planets Mercury and Earth are shown in blue.

Though the planet orbits its star from a distance comparable to that of Venus in our own solar system, it is actually cold. This is because its two parent stars are both smaller than the sun and don't give off as much heat.
