If the moon is numbered, but not named, use the designation with Roman numerals e.g. Jupiter LIV. If the moon is neither numbered nor named, use the provisional designation, e.g. S/2003 J 10. For moons of minor planets, follow the general titling policy.
From 1975 to 2009, the International Astronomical Union was assigning names to all planetary satellites, and Roman numerals were usually not assigned to satellites until they are named. (An exception is Saturn's moon Helene , which received the Roman numeral XII in 1982, but was not named until 1988.)
The Roman numbering system arose with the very first discovery of natural satellites other than Earth's: Galileo referred to the Galilean moons as I through IV (counting from Jupiter outward), in part to spite his rival Simon Marius, who had proposed the names now adopted, after his own proposal to name the bodies after members of the Medici ...
A classification system for neutron stars using Roman numerals has been proposed: type I for less massive neutron stars with low cooling rates, type II for more massive neutron stars with higher cooling rates, and a proposed type III for more massive neutron stars (possible exotic star candidates) with higher cooling rates.

However, roman numerals are read left-to-right, meaning a one in front of a "V" would translate to four. "L" stands for 50 and "C" stands for 100. While we're a ways away from getting to Super ...

(H is the chemical symbol for hydrogen, and "I" is the Roman numeral. It is customary in astronomy to use the Roman numeral I for neutral atoms, II for singly-ionized—HII is H + in other sciences—III for doubly-ionized, e.g. OIII is O ++, etc. [1]) These regions do not emit detectable visible light (except in spectral lines from elements ...
