Interplanetary medium, thinly scattered matter that exists between the planets and other bodies of the solar system, as well as the forces (e.g., magnetic and electric) that pervade this region of space.
Thus, the temperature of the interplanetary medium is still more than 200,000 K near Earth.

Among the inner planets, only Earth has a strong magnetic field, which shields it from the interplanetary medium.

Occasional giant solar flares, short-lived eruptions on the Sun's surface, expel matter (along with high-energy radiation) that contributes to this interplanetary medium.

Interstellar matter (ISM) sets the boundary conditions of the heliosphere and dominates the interplanetary medium.
In 2012 the space probe Voyager 1 crossed the boundary between the interplanetary medium and the interstellar medium a region called the heliopause.
The material components of the interplanetary medium consist of neutral hydrogen, plasma gas comprising electrically charged particles from the Sun, cosmic rays, and dust particles.
The magnetic field traps some of the electrically charged particles of the interplanetary medium inside a region around Earth known as the magnetosphere.
