Epimetheus and Janus are sister moons, orbiting Saturn. Both are potato shaped and share a similar orbit around Saturn. It is possible that they are the result of the breakup of one moon. Every 4 Earth years, they trade spaces in their orbits due to the gravitational interaction between the two bodies.

They both trail quite a bit of dust and particles (possibly due to impacts from foreign bodies), so that a faint ring, the Janus/Epimetheus Ring, shares their orbit. 

I started making them together on March 28th and could only finish them on April 2nd due to health issues. I had built the base and coiled the shape but needed to refine them and shave off a bit of clay. Thankfully I had wrapped them tightly and did not have to start again.
