Planetary phenomena refer to various natural events and processes that occur on planets, including their atmospheres, surfaces, and interactions with other celestial bodies. Examples include volcanoes, dust storms, and auroras, which can be observed on planets like Mars and Jupiter. These phenomena are influenced by factors such as gravity, temperature, and atmospheric composition. Additionally, planetary phenomena can also involve the movement of planets within the solar system, such as orbital patterns and eclipses. These events help scientists understand the dynamics of planetary systems and the conditions that may support life beyond Earth. Observing these phenomena contributes to our knowledge of the universe.
