Solar system configuration:
The sun contains 99.85% of all matter in the solar system, the planets are concentrated from the same reaction of matter that makes up the sun, containing only 0.135% of the mass in the solar system, and Jupiter contains more than double all mass of the solar system. other planets combined and makes up the rest. Planets, comets, asteroids, meteorites and interplanetary bodies, the remaining 0.015%. The following list is the most complete distribution list in our solar system: Sun: 99.85% Planets: 0.135% Comets: 0.01% ? Satellites: 0.00005% Minor planets: 0.0000002% Meteorites: 0.0000001% Interplanetary objects: 0.0000001%
Interplanetary space:
It is clear that almost all solar systems are empty space by volume, far from nothing. This space “space” contains interplanetary bodies and this contains various forms of energy, and is composed of two elements: interplanetary dust and interplanetary gas.
Interplanetary dust is made up of microscopic solid particles, and interplanetary gas is a stream of brittle gas and charged particles, mostly flowing from the sun and made up of protons and electrons called the solar wind. The solar wind can be measured by spacecraft and has a significant effect on comet tails, and it also has a measurable effect on the motion of spacecraft, as the solar wind has a speed of about 400 kilometers (250 miles) per second.
Sun:
The diameter of the closest star to us, the Sun, is 1,392,000 km, and the age of the Sun is believed to be 4.6 billion years. . percent.
At the center and core of the Sun, hydrogen fuses to form helium, and the energy of this process diffuses to the visible limits of the Sun and then out into space in the form of heat and light.
Because the sun is so big, it exerts a strong gravitational pull on everything in our solar system, and due to the gravitational pull on the sun, the earth rotates as it orbits the sun.
The sun has several layers:
The nucleus, the radiation zone, the convection zone and the photosphere (surface of the Sun). Furthermore, there are two layers of gas on the photosphere called the “chromosphere” and the “corona”. The sun emits a lot of radiation in addition to light and heat, as well as radio waves, ultraviolet and X-rays, and the earth’s atmosphere protects us from the harmful effects of ultraviolet and X-rays.
Are there differences between the planets in our solar system?

Planets come in different sizes, sizes, and colors, and the four planets closest to the sun are called “rocky” planets. It is small and similar in composition to Earth. They have no rings and only two of them (Earth and Mars) have moons.
The four outer planets, also called “gas giants”, are much larger than the rocky planets and all have rings and moons. Most of the gas giant planets are made up of hydrogen, helium, water ice, ammonia, methane and carbon monoxide .
Which planets are called “rocky” or “terrestrial” planets?
Mercury, Venus, Earth, and Mars are called “rocky” or “terrestrial” planets because they are similar in shape to Earth. The sun’s heat evaporates light elements such as hydrogen and helium in interplanetary space, often leaving rocks and minerals in this region and clumping together to form rocky inner planets.
Which planets are called “gas” planets?
Jupiter, Saturn, Uranus and Neptune are called “gas” planets. Jupiter and Saturn have the highest proportions of hydrogen and helium, while Uranus and Neptune contain the largest proportions of water ice, ammonia, methane and carbon monoxide.
Mercury:
Mercury is the closest planet to the Sun and orbits in a highly elliptical orbit from the Sun at 46 million km (29 million miles) to 70 million km (43.5 million miles). The rotation of the Sun takes about 88 Earth days, but it rotates on its axis once every 59 Earth days and, due to its slow rotation, takes a day on Mercury (from noon to noon) 176 Earth days and its axial tilt is 3/100 degrees. Much smaller than any other planet.
Mercury is very small, with a diameter of 4,878 kilometers (2/5 that of Earth) and only 5% of the mass of the Earth, and its surface gravity is one-third that of Earth.
Venus:
Venus is the second closest planet to the Sun and orbits in a nearly circular orbit at an altitude of 108 million km. Mercury orbits the Earth also close to any other planet in the solar system and can reach about 40 million km.
Venus takes approximately 225 Earth days to revolve around the sun, rotating clockwise at a very slow rate every 243 days. Only Uranus (which rotates almost on its side) also has a clockwise rotation. A day on Venus (dawn to dawn) lasts 117 Earth days.
Venus has a slight axial tilt of 3°, Venus has a diameter of 12,100 km, roughly the same size as Earth (1,000 km smaller) and has 80% of the Earth’s mass, with surface gravity equal to 90 % of that of the earth.

Globalism:
The third closest planet to the Sun is Earth, and it is the largest and densest of the inner planets. Earth rotates in a reasonably circular distance of 150 million kilometers and is the first planet to have a Moon. Earth, of course , is the only place we know of life.
It takes 365.25 Earth days to revolve around the Sun, and the length of a day on Earth (dawn to sunrise) takes 24 hours as it revolves around the Sun every 56 minutes and 4 seconds every 23 hours.
The Earth’s axial tilt is 23.4 degrees and the diameter is 12.742 km. The age of the Earth is believed to be 4.54 billion years, and is often accompanied by the Moon. The Moon was formed by the impact of a body larger than Mars and collected materials. Finally, on the Moon, the Moon had the effect of equalizing the Earth’s axial tilt, which was the source of the tides in the Brief of Egypt.
National anthem:
Mars is the fourth closest planet to the Sun and orbits in a slightly eccentric orbit of approximately 230 (+20) million km.
Mars takes approximately 686 Earth days to revolve around the Sun, has a similar inclination (25.1 degrees) and rotation time to Earth (24 hours 37 minutes), and day length (dawn to sunrise ) is 24 hours and 39 minutes. It has seasons like Earth, due to the tilt.
Mars has a diameter of 6792 km, which is half the size of Earth, but its mass is only one-tenth that of Earth, and Mars’ surface gravity is about 37% that of Earth.

Jupiter:
Jupiter, or Jupiter, is the fifth closest planet to the sun, and is the first among the so-called outer planets (outside the asteroid belt). It’s actually a point outside the surface of the sun.
Jupiter orbits the sun every 12 years (about 780 million km) and consists of a gas (75% hydrogen and 24% helium) and a rocky core surrounded by a sea of liquid metallic hydrogen which forms a sphere with a diameter of 110,000km. Jupiter has a diameter of 142,984 km.
Saturn:
Saturn is the sixth closest planet to the Sun and the second largest in the solar system, with a diameter 9 times (57,000 km) that of Earth and a mass 95 times that of Earth.
Saturn orbits the sun every 29 years (about 1400 million km) and consists mainly of gas (96% hydrogen and 3% helium) and is supposed to be a rocky core surrounded by a sea of liquid metallic hydrogen forming a ball with a diameter of about 56,000 km. The upper layers consist of liquid water, ammonium hydrosulfide, hydrogen and helium.
Saturn’s core is very hot (11,700 degrees Celsius) and generates more heat than it does from the sun. The further away from the planetary center, the lower the temperature, reaching about -180 °C in the upper atmosphere and 0 °C at a depth of about 350 km.

Uranus:
Uranus is the seventh closest planet to the Sun and the third and fourth largest planets, with a diameter (50,000 km) four times that of Earth, and a mass more than 14 times that of Earth.
Uranus orbits the Sun only once every 84 years (about 2,900 million km), but it is unusual in its rotation (with an axial tilt of 97 degrees), which means that even its moons and the faint system of rings rotate perpendicular to the plane of the ecliptic.
Neptune:
Neptune is the eighth closest planet to the Sun and is the last planet in the Solar System (since Pluto’s descent). It is similar to Uranus in size and composition, with a diameter of 49,000 km and a mass 17 times that of Earth. Neptune revolves around the Sun at a distance of about 4,500 million km every 165 years, or 30 times the distance from the Sun to the Earth, meaning that the power of sunlight on Neptune is 1% of its power on Earth, and Neptune rotates on an axis tilted 28 degrees every 16 hours relative to those on Earth.
“At the end of our solar system research, we have gathered some important information in this universe, which is full of information and secrets together. We’ve given you the tip of the iceberg, and the right search is always looking for more secrets, so don’t stop there.”
