Plot
It is 1980, and the United States Air Force's Space Exploration Wing has bases on the Moon and is on the eve of a mission to Mars. When another of its two-member crewed Pegasus spacecraft mysteriously disappears, rumors begin circulating of space monsters and phantom planets. Captain Frank Chapman and his navigator Lt. Ray Makonnen are ordered to investigate.
During the search, their spaceship suffers damage from a meteor shower, requiring that both men go outside to make repairs. A bullet-sized particle, however, pierces the air hose on Chapman's space suit, rendering him unconscious. Makonnen is able to repair the hose, but as he opens the airlock hatch, he is fatally struck by a similar particle. Makonnen's last act before being propelled into deep space is to push Chapman inside and close the airlock hatch. Chapman comes to and finds Makonnen gone and himself unable to communicate with the lunar base. He records a log entry about the preceding events, noting that he now must make a forced landing on an asteroid, that it is somehow pulling in his Pegasus spaceship.
Exiting his ship while still feeling the effects of the accident, Chapman collapses and sees tiny humanoids about six inches tall approaching. Once his helmet visor is opened, he can breathe but shrinks to their size due to the asteroid's atmosphere. He is taken underground.
Sesom, the aged and wise ruler of Rheton (the native name for the rocky and seemingly lifeless planetoid where Chapman has landed), explains that though his craft was brought down safely by their gravitational tractor beam, they had not been able to do the same with the preceding Earth spaceships that came near, which were completely destroyed, along with their crews, when they crashed on Rheton's surface. He informs Chapman that he never can leave but will have all the rights of a citizen of Rheton. As he slept, Chapman's spaceship was sent into space to keep Rheton's existence a secret, and more importantly, their world's gravitational technology, which allows the Rhetonians to navigate their world through space.
Chapman meets two beautiful women: Sesom's smugly spoiled blond daughter Liara and the gentle but mute black-haired Zetha. Liara is more than willing to answer his many questions about Rheton. Sesom informs Chapman that he later may marry one of the women once he has become accustomed to living on Rheton.
Liara, after following and engaging constantly with Chapman, declares her love for him, but Chapman, still eager to return to his own people, quietly rejects her. Herron, a young man who is in love with Liara, attempts to win her for himself by lying to Sesom, telling him Chapman is attempting to win over both women.
Stating that he believes this to be a crime against the people of Rheton, Herron requests a duel to the death. Chapman agrees, and the two engage in a form of combat where opponents must push each other onto gravity plates that cause immediate disintegration when touched. Just as Chapman is about to push Herron onto a plate, he lets Herron go, stating that he cannot kill someone for no reason.
As time goes on, Chapman and the mute Zetha become acquainted and eventually fall in love. Herron comes to Chapman late one night and offers to help him escape.
Any plans for the future, however, are put on hold when Chapman discovers the reason for Rheton's erratic course through space: It is because the planetoid is being attacked by the Solarites, an alien race of "fire people" from an unidentified "sun satellite". They want to destroy Rheton with their flaming fighter craft so they can steal its secret of gravitational control.
With Chapman's help, Sesom and Herron destroy the enemy fleet using a gravity beam. During the battle, a giant 7-foot tall Solarite prisoner, captured during a previous raid, escapes when the gravity barrier holding him fails. Stalking corridors, the creature captures Zetha, who previously had been traumatized into silence by a childhood encounter with the savage species. After Sesom is attacked by this bug-eyed monster, Chapman and Herron attempt to rescue Zetha. Chapman defeats the Solarite by pushing it onto a gravity plate.
While kidnapped, Zetha's muteness vanished when she saw Chapman about to be attacked by the creature, and she was able to scream, warning him. The return of her voice allows her to later confess her love for him. The two kiss, but Zetha knows that he must return to his home world. They are interrupted when a search party from Earth locates Chapman. In order to preserve the secret of his adopted people, Chapman crawls inside his spacesuit, and after once more being exposed to atmospheric gases from Earth, he returns to his normal size. Reluctantly, he goes with the search party, leaving Zetha and the miniature world of Rheton behind.
Production
Director William Marshall, a former actor and bandleader, had previously made two films, Hello God and Adventures of Captain Fabian, with Errol Flynn. His son Mike Marshall made his debut in The Phantom Planet. Screenwriter and co-producer Fred Gebhardt previously produced and wrote the screenplay for Columbia Pictures 1960 science fiction film 12 to the Moon. Star Dean Fredericks had just finished filming the lead in the NBC TV series Steve Canyon, which was later cancelled after its first season of 34 episodes. Co-star Francis X. Bushman had been a major film star in silent films. This was actor Richard Kiel's first credited film role in which he played the captured Solarite.
The Phantom Planet's interior spaceship sets, spacesuit helmets, oxygen backpacks, and special effects originally appeared in the Ziv Company's science fiction television series Men into Space, which was broadcast on CBS TV in 1959.
Reception
The Monthly Film Bulletin wrote: "A corny slice of SF hokum which seeks inspiration from all quarters. The Lilliputian idea quickly gets forgotten; the gravity control unit is operated by hand-waving and looks as if it should produce a tune (like musical glasses); a monster is to hand in the person of a captured Solarite, and though his appearance is brief it suffices to allow him to perform his function of carrying off the heroine. The only interest is the appearance of veteran Francis X. Bushman, who plays the Rheton leader."
Boxoffice wrote: "Fredericks is a right handsome, grim-visaged hero, given to acts of herculean feats. William Marshall's direction, conventionally developed, tells the story with little frills."

Mystery Science Theater 3000
The Phantom Planet was featured in episode #902 of Mystery Science Theater 3000 (MST3K), debuting March 21, 1998, on the Sci-Fi Channel. Writer/performer Bill Corbett noted the movie's "many scenes of non-stop expositional chat", which made it a difficult episode to write for, as well as the similarity of actor Coleen Gray's role with her previous "devious vixen" role in The Leech Woman.
Writer Jim Vorel ranked the episode #91 (out of 197 total MST3K episodes) in his ranking of the series' first 12 seasons. Vorel writes The Phantom Planet is "both silly and introspective" and "takes itself considerably more seriously than anyone in the audience" could have while displaying "campy special effects ... during the rocketry scenes." Vorel also noted "anything involving the 'combat rod,' a wishbone-shaped stick that the aliens use to compete in inane gladiatorial games," was the film's highlight.
