Outer space
Interplanetary space is the space around the Sun and planets of the Solar System. It has  the solar wind, a continuous stream of charged particles from the Sun. This stream creates a very thin atmosphere (the Heliosphere) for billions of miles or kilometers into space. Interplanetary space has the magnetic field generated by the Sun. Planets such as Jupiter, Saturn, Mercury and the Earth also have Magnetospheres.  These magnetic fields can trap particles from the solar wind and other sources, creating belts of magnetic particles such as the Van Allen radiation belt. Planets without magnetic fields, such as Mars, have their atmospheres gradually stripped off by the solar wind.
