Space Small Object Dataset(SSOD) consists of 9822 annotated astronomical optical images, all of which have a uniform size of 1340*1300. The dataset encompasses various scenarios, including noise interference caused by starlight and ground light, trailing of target stars, and overexposure. It encompasses single stars, multiple stars, and dense star fields, with the latter referring specifically to cases where the number of objects in a single image exceeds 50.
