👉 Meteoritics is a scientific discipline that deals with the study of the Earth's atmospheric gases, including nitrogen, oxygen, carbon dioxide, and water vapor. The term was first used in the early 20th century to describe the atmosphere of Mars, which is believed to be composed primarily of these gases. However, meteoritics has since expanded to include studies of other planets and moons in our solar system as well as space exploration phenomena such as the formation of comets and asteroids.
