Measurement of the Earth's distance to the moon

On the occasion of World astronomy day and the eighth student astronomy seminar, Mohammad ibn Zakariya Razi student research center in Shahr-e Ray launched an international project with the title of “Measuring Earth to Moon distance using non-Euclidean trigonometry” with the cooperation of America, India, and Italy, Thailand. A large population of students in the participating countries took part in the project. Moreover, different national astronomy groups and societies cooperated. The present article seeks to provide practical astronomical and mathematical training on international level, so that students will be able to confirm figures and numbers discussed in scientific books and centers. In these measurements, students in Rey research center astronomy group took part in measuring the moon azimuth angle and its elevation in Picard region on its surface. The measurement results along with other tests performed by national and foreign groups showed an appropriate level of adaptability with pre-measured standard values.
