The invention belongs to the technical field of aviation detection and provides a fixed star and earth ultraviolet limb detection device and a detection method. The device comprises a fixed star detection lens, and four earth limb detection lenses which are symmetrically and uniformly distributed around the fixed star detection lens and of which the observation visual axis direction points to thecenter of the earth, wherein the image sensor comprises four circular areas used for receiving images detected by the four earth limb detection lenses respectively and a central circle area located inthe four circular areas, and an imaging range area of the fixed star detection lens (1) is located in the central circle area; the fixed star detection lens is used for imaging a fixed star in a central circle area, and the four earth limb detection lenses are used for imaging a unilateral part annulus of an earth limb on the circular area so as to observe a star body. The detection device is large in limb observation ang
