Kepler-452 system compared to our solar system

This size and scale of the Kepler-452 system compared alongside the Kepler-186 system and the solar system. Kepler-186 is a miniature solar system that would fit entirely inside the orbit of Mercury.

The habitable zone of Kepler-186 is very small compared to that of Kepler-452 or the Sun because it is a much smaller, cooler star. The size and extent of the habitable zone of Kepler-452 is nearly the same as that of the Sun, but is slightly bigger because Kepler-452 is somewhat older, bigger and brighter. The size of the orbit of Kepler-452b is nearly the same as that of the Earth, at 1.05 AU. Kepler-452b orbits its star once every 385 days.
