Abstract: Astrotourism, also known as stellar tourism, involves the development of recreational and educational activities related to the cosmos and astronomical phenomena. This type of special interest tourism focuses on nature, culture, and conservation, and stands out for its exceptional economic, social, and cultural benefits. The aim of the study was to analyze the scientific production on astrotourism based on PRISMA guidelines and a review of the Web of Science and Scopus databases (up to December 2022). The applied methodology consisted of bibliometric analysis and mapping of the literature, carried out using the Bibliometrix program, which found a total of 45 articles in 36 journals. The results revealed a growing scientific production, concentrated in few journals, scattered among multiple authors, and limited thematic diversity divided into twelve clusters, which were classified using the Callon algorithm (niche, motor, basic, and emerging/declining themes). It is concluded that astrotourism is a dynamic and consensual topic of study regarding its regional sustainable development contribution and educational capacity on the heritage and aesthetic value of the skies.
