What is the scientific field dedicated to the study of heavenly bodies, celestial objects, and phenomena originating beyond Earth's atmosphere? [#2487]

Astronomy is a natural science that involves the scientific study of celestial objects (such as stars, planets, comets, galaxies, and nebulae), the universe as a whole, and the phenomena that originate beyond Earth's atmosphere. It uses principles of mathematics, physics, and chemistry to understand their origin, evolution, physical and chemical properties, and behavior. While cosmology is a branch of astronomy that focuses on the universe's origin, evolution, and large-scale structure, astronomy encompasses the broader study of all extraterrestrial objects and phenomena.

384,400 KM. The average distance between Earth and the Moon is 384,400 kilometers (238,855 miles). This is about 30 times the diameter of Earth. The Moon’s orbit around Earth is elliptical, so the distance between the two bodies varies slightly. The semi-major axis has a value of 384,399 km (238,854 mi). The time-averaged distance between the centers of Earth and the Moon is 385,000.6 km (239,228.3 mi). The actual distance varies over the course of the orbit of the Moon, from 356,500 km (221,500 mi) at the perigee to 406,700 km (252,700 mi) at apogee, resulting in a differential range of 50,200 km (31,200 mi).
