Pronounced impact craters covered the surface, so much so that it resembled a warmly lit class D planet without an atmosphere. From its surface, though, the capital city seemed to have blue-green skies.
- Lines are sketched in most images of the planet's sky that might suggest the city was domed, but this detail was not addressed.
Lothor's capital includes a government house facility and a presidential banquet hall that often serves several hundred people. A spaceport or airport with hovercars and winged aircraft was located not far from the government complex.
In 2269, the Federation starship USS Enterprise was dispatched to Lothor to secure a defensive alliance against the Klingon Empire. But Klingon spies intercepted Starfleet's orders, and before the Enterprise arrived, a small Klingon force landed on Lothor and mass-hypnotized the Lothorian government.
Most of the Enterprise crew visited the planet's surface to attend a grand banquet, where they were hypnotized by the Klingons. Later, while under orders by the Klingons to stop James T. Kirk and Spock, the Lothorian president blew up the government complex. (TOS comic: "By Order of the Empire")
