Remus

Romulus

An unnamed Minshara class planet claimed by the Star Empire and protected by a minefield in 2152.

The following is a list of mentioned planets and star systems in the Romulan Star Empire. All planets listed are or were inhabited at some point of time.

Planets

The reference book Star Trek: Federation - The First 150 Years identifies the Romulan planet shown in ENT: "Minefield" as Unroth III.
Since the expansion of the Romulan Star Empire is most likely based upon conquest and not the peaceful admission of single planets, it is possible that, if one planet is Romulan, the whole system may be seized by the Star Empire, too.

Stars, star systems and other stellar phenomena

Tranome Sar was mentioned as the site of a battle between the Klingons and the Romulans, therefore it might be a planet or star within the Romulan Star Empire.
Tomed may be the location of the Tomed Incident, which involved the Federation and the Romulans, so Tomed may be a planet or star within the Romulan Star Empire.
D'deridex and Gasko share names with Romulan ships, so they may be planets or stars within the Romulan Star Empire.
