The Phantom Planet1961

Horror Vault's take

When a mysterious asteroid exerts an irresistible pull on a lone astronaut's spacecraft, he finds himself stranded on a world that operates by rules entirely unlike our own. The planet's strange atmosphere triggers a startling physical transformation, leaving him at the mercy of an alien society with its own conflicts and dangers. Caught between worlds — literally and figuratively — he must navigate an unfamiliar civilization with no guarantee of ever returning home. This early-sixties sci-fi curio blends Cold War-era space anxiety with creature-feature sensibilities.
