Class R Planet

Here today, gone tomorrow. That’s your average Class R planet. Think ‘R’ as in ‘rogue,’ which is the label given to these worlds by Star Charts. Class R worlds vary in size from around that of Mercury up to a bit larger than Earth and do not orbit stars. You’ll find Class R planets in interstellar space or in cometary halos. The surface environment of Class R worlds may be suitable for life as it is warmed by geothermal venting, which also provides the gases that make up the atmosphere. These rogue planets may be home to non-photosynthetic plant life and animal life.

Examples of Class R Planets


The planet Dakala was visited by the Enterprise NX-01 in the aptly named episode “Rogue Planet.”
