Trantor_Class
Most civilized species that achieve spaceflight move their polluting heavy industries off-planet, and humans are no exception. Trantor-class planets are worlds humans have industrialized in an attempt to leave their inhabited planets natural and pleasant. They are typically transformed from worlds that had no indiginous ecosystem to destroy, such as airless rocky worlds or worlds with reducing atmospheres. Sometimes they are terraformed with a minimalistic imported ecosystem (often consisting of genetically engineered bacteria used to remediate industrial waste), but sometimes they are left uninhabitable, with the population confined to bases and domes.
Trantor class worlds are typically heavily mechanized, with most of the industry being done by robotic factories and automated mines. Populations range from a few tens of thousands to several million, and usually consist of technicians, engineers, overseers, and industrialists on temporary shifts from more amenable planets. Trantor class worlds often have exclusive contracts for their manufactured goods, so they are poor sources of trade goods, but they provide a market for natural products. Trantor class planets usually host a substantial aerospace production industry and are good sources for starships and upgrades.

Bio_Simple
Planets that carry the Bio-Simple designation are planets in the early stages of evolving carbon/water based life. They have atmospheres which vary from strongly reducing (methane, ammonia, and carbon dioxide) to weakly oxidizing, with some unusual cases having hydrogen-helium atmospheres or atmospheres consisting almost entirely of noble gases. All have liquid water present in some amount. Most have substantial volcanic activity and highly unstable climates. Climates vary from planets covered entirely in ice with oceans underneath, to planets where only the poles are cool enough to be life-bearing (and in rare cases, where they are inhabitable only part of the year, with the indigenous life-forms going into endospore or endolithic life-cycles during the uninhabitable summer.)
Life forms on Bio-Simple planets vary from primitive self-replicating molecular communities, through bacteria-analogues, all the way up to complex eukaryote-analogues that contain several to dozens of different types of endosymbiote. Generally, any planet with multicellular life forms is considered Bio-Diverse, although exceptions are sometimes made in cases where only a few species of multicellular life-forms exist, and they are considered overspecialized evolutionary dead-ends.
Bio-Simple worlds are almost always uninhabited due to the typically reducing atmosphere and the danger of alien pathogens (the particular combination of planetary microbial communities and fast evolutionary environment can generate especially deadly diseases.) Most races also feel a responsibility to avoid interfering with the developing lifeforms, so they are also rarely terraformed. Most Bio-Simple worlds have unmanned scientific observation posts that can be landed at, although they provide no goods or services besides that of basic system network access.
