Meteoroid research involves the study of small rocky or metallic objects that travel through space and enter Earth's atmosphere. These objects are typically smaller than asteroids and are often referred to as shooting stars or meteors when they burn up upon entry into the atmosphere. Meteoroid research aims to understand the properties, origins, and trajectories of these objects, as well as their potential impact on Earth and other celestial bodies. Scientists use various techniques, such as observations, simulations, and analyses of recovered meteorites, to study meteoroids and gain insights into the formation and evolution of the solar system.
