Solar system setup:
The sun contains 99.85% of all the 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 of the solar system, and Jupiter contains more than twice all the other planets combined and makes up the rest. Planets, comets, asteroids, meteorites and interplanetary bodies, the remaining 0.015%. The list below is the most comprehensive 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 in volume, far from nothingness. This “space” space contains interplanetary bodies and this contains various forms of energy, and is composed of two elements: interplanetary dust and interplanetary gases.
Interplanetary dust consists of microscopic solid particles, and interplanetary gas is a stream of fragile gas and charged particles, mostly flowing from the sun and consisting 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 spacecraft motion, as the solar wind has a speed of regarding 400 kilometers (250 miles) per second.
Sun:
The diameter of the nearest star to us, the Sun, is 1,392,000 km, and it is believed that the age of the Sun is 4.6 billion years. . percent.
At the core and core of the Sun, hydrogen fuses to form helium, and the energy from 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 force on everything in our solar system, and because of the gravitational force on the sun, the earth rotates as it orbits the sun.
The sun has several layers:
The core, radiation zone, convection zone, and photosphere (surface of the Sun). In addition, there are two layers of gas on the photosphere called the “chromosphere” and the “corona”. The sun emits a lot of radiation besides 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 don’t have 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 they have all rings and moons. Most of the gas giant planets consist of hydrogen, helium, frozen water, 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 Earth-like in shape. 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.
What 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 share of frozen water, ammonia, methane and carbon monoxide.
Mercury:
Mercury is the closest planet to the Sun and orbits in a very 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 regarding 88 Earth days, but it rotates on its axis once every 59 Earth days, and because of its slow rotation, it takes one day on Mercury (from midday to noon) 176 Earth days, and its axial inclination is 3/100 degrees . Much smaller than any other planet.
Mercury is very small, with a diameter of 4,878 kilometers (2/5 of Earth’s) and only 5% of Earth’s mass, and its surface gravity is one-third of Earth’s.
Venus:
Venus is the second closest planet to the Sun and orbits in an almost circular orbit at an altitude of 108 million km. Mercury also orbits Earth as close as any other planet in the solar system and can reach regarding 40 million km.
Venus takes regarding 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 (from sunrise to sunrise) lasts 117 Earth days.
Venus has a slight axial tilt of 3°. Venus is 12,100 km in diameter, roughly the same size as Earth (1,000 km smaller) and has 80% of Earth’s mass, with gravity at the surface of 90% of Earth’s.

Globalism :
The third planet closest to the Sun is the Earth, and it is the largest and densest among the inner planets. The Earth rotates in a reasonably circular distance at 150 million kilometers and is the first planet to have the Moon. The 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 (from sunrise to sunrise) takes 24 hours as it revolves around the Sun every 56 minutes and 4 seconds every 23 hours.
The axial tilt of the Earth 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 it is often accompanied by the Moon. The Moon was formed from 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 planet closest to the Sun and orbits in a slightly eccentric orbit of regarding 230 (+20) million km.
Mars takes regarding 686 Earth days to revolve around the Sun, has an inclination (25.1 degrees) and a rotation time similar to Earth (24 hours and 37 minutes), and the duration of the day (from sunrise to sunrise) is 24 hours and 39 minutes. It has seasons like Earth, because of the tilt.
Mars has a diameter of 6792 km, which is half the size of Earth, but its mass is only one tenth of Earth’s, and the surface gravity of Mars is regarding 37% of Earth’s.

Jupiter:
Jupiter, or Jupiter, is the fifth planet closest to the sun, and it is the first among the so-called outer planets (outside the asteroid belt). It is actually a point outside the surface of the sun.
Jupiter orbits the sun every 12 years (regarding 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 that forms a ball with a diameter of 110,000 km. Jupiter has a diameter of 142,984 km.
Saturn:
Saturn is the sixth planet closest 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 (regarding 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 regarding 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 farther from the planetary center, the lower the temperature, reaching regarding -180 °C in the upper atmosphere and 0 °C at a depth of regarding 350 km.

Uranus:
Uranus is the seventh planet closest to the Sun and the third and fourth largest planet, with a diameter (50,000 km) four times that of Earth, and a mass of more than 14 times that of Earth.
Uranus orbits the Sun only once every 84 years (regarding 2,900 million km), but it is unusual for it to rotate around itself (with an axial tilt of 97 degrees), which means that its moons and the weak ring system also rotate in a plane perpendicular to the plane of the ecliptic.
Neptune:
Neptune is the eighth planet closest to the Sun and is the last planet in the Solar System (since the descent of Pluto). 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 regarding 4,500 million km every 165 years, or 30 times the distance from the Sun to Earth, meaning the power of sunlight on Neptune is 1% of its power on Earth, and Neptune rotates on an axis inclined 28 degrees every 16 hours. away from those on Earth.
