Comet was a pulp magazine which published five issues from December 1940 to July 1941. It was edited by F. Orlin Tremaine, who had edited Astounding Stories, one of the leaders of the science fiction (sf) magazine field, for several years in the mid-1930s. Tremaine paid one cent per word, which was higher than some of the competing magazines, but the publisher, H-K Publications, was unable to sustain the magazine while it gained circulation, and it was cancelled after less than a year when Tremaine resigned. Comet published fiction by several well-known and popular writers, including Jack Williamson, E.E. Smith, Robert Moore Williams, and Ross Rocklynne.
