Romilly

Intro
Romilly is the third (semi major axis wise) and last (apoapsis wise) planet orbiting Murph. It is an ice planet with lakes of water, and has one of the highest eccentricities of any terrestrial planet discovered so far, of 0.96.

Supposed orbit
It was thought that Romilly shared similarities with Doyle, but it was moving too fast to be in a circular orbit. Instead, its orbit was extremely eccentric, similar to that of a comet.
