outer




Terrestrial space: It is the region near the Earth, which contains the upper region of the atmosphere and the magnetosphere. The outer space of the Moon: It is the area between the Earth's atmosphere, the orbit of the Moon, and the Engerange points. Interplanetary space: It is the reality between the sun and the solar system, where the planets dominate it, extending from the sun's atmosphere to the end of the long tail outside the planets, and it includes: Mercury, Venus, Mars, Earth, Jupiter, Saturn, Uranus and Pluto, in addition to gas. , dust, small meteorites, and plasma. Interstellar space: It is a physical space found in the galaxy, where no stars or planetary systems occupy it. This space is formed from hydrogen and helium atoms.

space temperature The temperature of outer space is estimated between five and six kelvin by estimating the radiation of stars, and the first was estimated by the physicist Charles Edouard Guillaume. The sea, which is called the Carmen Line, and the purpose of which is to record atmospheric measurements and treaties in space.

 space definition Outer space is the space between celestial bodies, including planet Earth. It is not completely empty, but consists of a relativistic vacuum made up of a low density of particles (particles), mostly hydrogen and helium plasma, as well as electromagnetic radiation, magnetic fields, and neutrons. Recent observations prove that it contains dark matter and energy as well. The baseline temperature, determined by the residual radiation from the Big Bang, is 2.7 K. Plasma with extremely low density (less than one hydrogen atom per cubic meter) and high temperature (millions of degrees Kelvin) in intergalactic space accounts for most of the normal baryonic problem in outer space; Local concentrations have been condensed into stars and galaxie s .
