Kepler's Fantasy is a close planetary binary system where each planet completes an orbit in half a day. The first planet is the larger of the two and has a Taylor ring system. Such ring systems are famous for being extremely small in width: sometimes they are not even noticeable until the final approach to a planet. This particular ring system is only 2,080 km wide.

What is peculiar about this system however are the four moons that orbit the ringed planet: such Taylor-ringed planets (that are in a binary pair) having one moon is rare enough, but having four of them is incredibly rare.

The first two moons (1 a and 1 b) are a binary pair, with their barycentre practically hugging the rings, itself orbiting the planet in 3.12 hours.

The third moon (1 c) orbits just beyond the orbital path of the other two, passing by them every so often.

The fourth moon (1 d) is noticeably larger in diameter than the inner moons. Although its orbital distance is still close to the inner moons, its orbital path is significantly inclined at -44.38°. The surface of this moon is a great spot to view the entire moon system from above, and the second planet is also a good place to view it from.
