Interplanetary Medium

The interplanetary medium is the space between planets in our solar system, filled with gas, dust, and charged particles, primarily from the Sun. This medium is not empty; it is a dynamic environment influenced by solar wind—a stream of particles ejected from the Sun. These particles interact with the magnetic fields of planets, affecting atmospheres and space weather. Understanding the interplanetary medium is crucial for studying cosmic events, satellite operations, and potential impacts on Earth, helping scientists learn about the complex interactions between solar activity and the space surrounding our planet.
