Planet Mok is a planet featured once in the Spaceman Spiff universe. Mok appears yellow from space and is orbited by at least two moons (one of them ringed); its surface, from what is seen of it, appears to consist of curvy, rocky hills. Spiff crash-landed on the planet after being shot down by unnamed spacefaring aliens (see left). Spiff described the planet as hostile and gave away its name before even landing, indicating that it had been charted. Little is seen of the planet apart from its alien inhabitants (see right), which take Spiff prisoner and interrogate him like in so many Spaceman Spiff comics.
