The burgeoning niche of astronomy tourism presents a unique confluence of education, leisure, and environmental sustainability, poised for significant growth within the global tourism industry. This study explores the critical role of Key Performance Indicators (KPIs) in optimizing the management, promotion, and development of astronomy tourism experiences. Employing a mixed-methods approach that combines quantitative data analysis with qualitative stakeholder insights, the research identifies pivotal KPIs across three main areas: Tourist Satisfaction Rates, Partnership Effectiveness, and Sustainability Measures. Findings highlight the Net Promoter Score (NPS) and repeat visitation rates as essential metrics for assessing customer satisfaction, while the impact of strategic partnerships and sustainability initiatives underscores the need for collaborative and environmentally responsible practices. This paper discusses the alignment of these findings with existing theories in tourism management and suggests practical strategies for practitioners to leverage KPIs for enhancing tourism experiences, promoting sustainability, and improving operational efficiency. Acknowledging certain limitations, including the scope of data collection, the study proposes directions for future research, emphasizing the expansion of KPI scope, cross-cultural consumer behavior exploration, and the economic impact analysis of astronomy tourism. This research contributes to the theoretical and practical understanding of managing astronomy tourism, offering insights into leveraging KPIs for strategic advantage in this niche yet rapidly evolving sector.
