Same as Fig. 3, but now assuming an Earth-sized planet around a Sun-like star. For comparison,the orbital distance of the Moon around the Earth is indicated with an “M”. The Earth’s Hill radius is located at 235 Earth radii, or 2.15 solar radii, beyond which moons are dynamically unstable. Prograde moons are unstable beyond about half the Hill radius. The analytical solutions were truncated at 218 Earth radii for b = 0 (solid white line) and at 189 Earth radii for b = 0.5 (white dashed line), respectively.
