Thanks to billions of years of cohabitation with Romulus, Remus has developed enormous mountain ranges across most of its surface. Similar instances of this sort of behavior have been recorded on moons of very large planets. The tectonic plates rise and fall in tides, just as the oceans of smaller planet-moon configurations have been known to do. This generates extra heat from friction and helps to circulate planetary magma. In effect, the rate of geological reshaping is greatly increased.

Ch'Havran (the Romulan name for Remus) is not nearly as nice a place as Romulus. It is as habitable as some of the best M-class planets, but its ecology and climate can appear to be much worse when compared to its pristine sister. Throughout its history, ch'Havran has suffered droughts, famines, and catastrophic storms. These are all commonplace events on other worlds, but almost unheard of on Romulus. As a result, ch'Rihan has attracted some of the less fortunate of the Romulan people, decreasing its efficiency as a contributor to the Romulan Star Empire.

Remus is, nevertheless, still one of the Homeworlds that make the Romulan Star Empire possible. Its turbulent past has provided the Romulans with many resources in the past. Revolution was perhaps the chief export of this planet in the past, but today, thanks to technological advances, Remus is a prime producer of agricultural goods and a key player in Imperial life.
