Comets
Comets are small celestial bodies that orbit the Sun and are composed of ice, dust, and rocky particles. As they approach the Sun, the ice in the comet's nucleus vaporizes, creating a glowing coma and sometimes a tail that can extend millions of kilometers. The study of comets provides important information about the early solar system and the formation of planets. Comets can also pose a potential threat to Earth if their orbit brings them too close to our planet, as they can collide and cause significant damage. Therefore, understanding the behavior and trajectory of comets is crucial for space and astronautical engineering. Scientists use various instruments and techniques, such as telescopes, spacecraft, and computer simulations, to study comets and their properties.
