== Material to be used ==
In the Solar System often there is a Solar Wind. This is a flow of [[Plasma (physics)|Plasma]]. The Solar System is located in one of the arms of the Milky Way galaxy. The Milky Way galaxy contains about 200 billion (200,000,000,000) stars.

== Trans-Neptunian region ==
The area beyond [[Neptune]] is called the "[[trans-Neptunian object|trans-Neptunian region]]" (
Latin: ''trans'' prep + acc -; across, over, beyond). We have not explored here very much. The region has a large number of small bodies. These bodies are mostly made up of rock and ice. The trans-Neptunian region is sometimes called the "outer Solar System", though those words are used more often to describe the region beyond the [[asteroid belt]].

Eris (68 AU) is the largest known scattered disc object. There has been a debate on weather or not it should be described as a planet. This is because it is 25% larger than Pluto and it is around the same distance across. It is the largest known dwarf planet in the Solar System. It has one moon, [[Dysnomia (moon)|Dysnomia]]. Eris and Pluto have a similar orbit.
