 Interplanetary medium

The interplanetary medium refers to the matter and radiation that exist in the space between the planets in our solar system. This medium is primarily composed of: 1. **Solar Wind**: A stream of charged particles (mostly electrons and protons) ejected from the sun's outer layers. The solar wind permeates the entire solar system and significantly influences space weather. 2. **Interplanetary Dust and Gas**: Tiny particles and gas molecules that exist in the space between planets.
