Definition of outer space, what it consists of, where it is located and how it presents itself, with the fundamental characteristics and elements contained in it.
Infinite outer space
Cosmic space is nothing, or almost nothing, exists between the Earth and the Moon, between the planets of the Solar System and between the stars, in practice it can be represented as the void that is found between the celestial bodies not containing air.
A fraction of space, the size of a house, contains few gas atoms and, perhaps, some specks of dust. Here and there meteoroids and comets move through space.
The little dense particles contained in space are mainly composed of hydrogen and helium, electromagnetic radiation, magnetic fields and neutrinos.
Some theorists suggest that previously unknown forms of matter and energy are also contained in outer space, where the density of matter can be represented with a reduced size only to a few hydrogen atoms per cubic meter.
