Pianeta caratterizzato da piogge torrenziali, odore di vegetazione in decomposizione e fiumi di fango, caratteristiche ritenute gradevolissime dai Ferengi (The Magnificent Ferengi).
Il clima di Ferenginar è talmente umido, che la lingua ferengi ha 178 parole differenti per indicare la pioggia.
Ecco come viene descritto il pianeta nello script di Family Business: «Ferenginar, the homeworld of the Ferengi, is a fetid dismal
swamp, subject to a near-endless downpour. The capital city
of the homeworld rises out of the swamp, a series of dome-
like structures piled almost haphazardly one atop another.
One particularly tall structure rises out of a marketplace
in the center of the city. It's a series of domes, one
stacked on the other, reaching to the sky like a high-tech
Angkor Wat. It's topped with a long, needle-like spire.
This is the Tower of Commerce in the Sacred Marketplace, the
center of all Ferengi civilization.»
