Distance of planet – Eight planets in our solar system are orbiting the sun in their orbits. These eight planets in terms of the average distance from the sun are, respectively, rocky planets: Mercury, Venus, Earth, Mars, these planets are relatively small and are mostly composed of rock, and have few moons or no moons at all. And gas planets: Jupiter, Saturn, Uranus, and Neptune, commonly referred to as Jupiter planets, are large planets composed mostly of gases with unstable atmospheres, and massive storms in the upper layers of their atmosphere due to convection, cold gas. It replaces hot gas and they often have a large number of moons. It should be noted that Pluto was removed from the solar system in 2006 and joined the dwarf planets. The inner planets are closer to the sun and the outer planets are farther away. The material of rocky planets is made of dust and rocks and, conversely, the material of gaseous planets is made of much lighter material. Planets were forming billions of years ago. The heavy matter could not escape the sun’s gravity much, but the lighter matter could move farther away from the sun and gradually formed gas planets. So the planets are farther away from gas and the planets closer are the currency of rock and metal. In the orbital belt of gas planets and rocky planets, there is an asteroid belt that is located approximately between the orbits of Mars and Jupiter. There are a large number of irregularly shaped space objects in this region called asteroids. About half the mass of the asteroid belt is made up of four large asteroids called Ceres, Vesta, Palace, and Hajia.

The sun alone makes up 99% of the mass of the solar system. The solar system is made up of many members that can be divided into four categories: the sun, dwarf planets, small objects, and planets. The planets follow the Kepler and Newton laws in their orbits around the sun in elliptical orbits. they say. Now, we will briefly describe the physical conditions as well as the distance of the planets of the solar system, respectively, from the planet closest to the sun to the farthest from them. We have written the distance between the planets and the sun in kilometers, we also used the astronomical unit or AU, which is a unit of length and each unit is equal to 149,597,870.7 kilometers, which is the approximate distance from Earth to the sun (150 million kilometers). is.

Planet of the system 

Mercury – Distance of planet
Mercury is the closest planet to the Sun and is very similar to the Moon. It is a rocky gray planet covered in volcanic craters. One side of Mercury is always facing the sun and the other side is facing the sun. The temperature of Mercury on the dayside reaches 430 degrees Celsius; That is, the temperature at which lead metal melts. On the night side, the temperature of Mercury drops to -183 degrees Celsius. Mercury orbits the sun once every 88 days. There is no atmosphere on Mercury, but some studies have shown a small amount of helium gas, which is said to have been orbited by the sun. Mercury does not have a moon.

Distance of planet

The closest distance from Mercury to the Sun: 46 million km (0.307 AU)
Distance from Mercury to the Sun: 70 million km (0.466 AU)
The average distance from Mercury to the Sun: 57 million km (0.387 AU)
Mercury distance to Earth: 77,300,000 km

Venus is always covered with dense clouds. For this reason, the surface of the rock of this planet can not be seen. In 1991, the Magellan spacecraft used radar to map the surface of Venus. Radar waves, after passing through the clouds and dense atmosphere of Venus, hit its surface and were reflected again. The Magellan spacecraft orbited Venus many times, completing some of the planet’s surface map in each orbit. No living thing can live on Venus, because its temperature is over 450 degrees Celsius. The Venus Express spacecraft, which has been orbiting the planet since 2005 and has received a lot of information, will fall from a distance of 80 km to the planet due to the end of its fuel during a research and suicide operation, and information about storm clouds and atmosphere. Get the planet. Venus does not have a moon.

The closest distance from Venus to the Sun: 107 million km (0.718 AU)
The farthest distance from Venus to the Sun: 109 million km (0.728 AU)
The average distance from Venus to the Sun: 108 million km (0.722 AU)
The closest distance from Venus to Earth: 40 million km

the earth – Distance of planet

The earth has very unique conditions. None of the other planets have oxygenated liquid water and atmosphere, and there is no life on them. The gradual evolution of the Earth, which has lasted 4.5 billion years, will continue naturally and as a result of human activities. Earth is also denser than all other planets. The Earth’s atmosphere contains gases that protect living organisms from the sun’s harmful rays. At the same time, the Earth’s atmosphere allows sunlight and heat to pass through. Plants make food and grow using sunlight. The inner planets consist of an inner core and an outer core with layers of molten, semi-molten, and solid rock. The inner core is metal and solid and is surrounded by the outer core, which is metal and molten. The moon is the only natural moon on Earth, covered with rock, and a quarter of the diameter of the earth. The moon has no light of its own, but it reflects sunlight and becomes visible.

The closest distance from Earth to the Sun: 147 million km (0.98 AU)
The farthest distance from Earth to the Sun: 152 million km (1.1 AU)
The average distance from Earth to the Sun: 150 million km (1 AU)

Distance of planet

Mars is the fourth planet in the solar system to move in a long orbit above Earth and at a slower speed than Earth. Each time it orbits the sun, it lasts 687 days (Earth day), and night and day are slightly longer than Earth. The planet is about one-half the size of Earth and has a diameter of 6790 km. Mars, the red planet of the solar system, is half the diameter of Earth, and its surface area is equal to the area of ​​land on Earth. Just like the earth, it has polar ice caps, deep valleys, mountains, dust, storms, and seasons. In its plains, like the moon, impact craters from the impact of celestial rocks can be seen. Despite its small size, the tallest mountain and largest valley in the solar system has been found on the planet. Mars has two small moons that take their letters Phobos (fear) and Dimos (horror) from the mythical companions of the war god Mars (Mars).

The closest distance from Mars to the Sun: 205 million kilometers (1.38 AU)
The farthest distance from Mars to the Sun: 249 million km (1.66 AU)
Average Mars to Sun: 228 million km (1.52 AU)
The distance from Mars to Earth is 55 million kilometers
