simple and easy a comet a comet has a solid center nucleus that contains rock particles trapped in frozen liqud
this forms the tail: as it moves closer to the sun the "outer ice" turns to gas and the solid particles (pieces) turn to dust
An increase in the space between particles is called expansion. This phenomenon typically occurs when a substance is heated, causing its particles to gain energy and move apart. Expansion can be observed in various states of matter, including solids, liquids, and gases. In gases, for example, the increase in space between particles leads to a decrease in density.
This behavior is characteristic of gases. Gases consist of particles that are far apart and move randomly, causing the gas to fill the container it is in. The lack of strong forces between gas particles allows them to spread out to fill the available space.
Democritus
these particles are called quarks
Gases are easily compressed because of the large amount of space between their particles. In a gas, particles are far apart and move freely, allowing them to be pushed closer together when pressure is applied. This compressibility is a key characteristic that distinguishes gases from liquids and solids, which have particles that are much closer together and resist compression.

Normally free floating particles and gases such as oxygen, nitrogen etc.
The winds of outer space are called solar winds. Not really air but it is the movement of gases and charged particles coming from the sun or the planets into outer space.
cause the particles have alot of space
Democritus
It is called compressibility. The compressibility of gases can be explained by the kinetic particle theory: due to the large amount of space between the gas particles and the weak attraction forces between them, gases can easily be compressed (the particles are brought closer to each other, thus reducing the volume of the gas).

A big ball of hot gases in space is called a star.
