The number of planets in the solar system
The solar system consists of the sun, and 8 planets revolve around it: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. On its shape, it also revolves around a star; Like the sun, in a special orbit and characterized by its huge size, according to the British Britannica website. In this report, “Al-Watan” reviews the number of planets in the solar system, and the features and characteristics of each planet.
Planets of the solar system in order
Mercury
It is the closest planet to the sun, and it is the smallest planet in our solar system.
It is characterized by being a rocky planet with an equatorial diameter of 1516 miles.
Mercury is not surrounded by an atmosphere, which leads to the instability of the temperature on its surface, changing from 840 degrees Fahrenheit during the day to -275 degrees Fahrenheit during the night.
Flower
It is the second closest planet to the sun, and it is the hottest planet at 863 degrees Fahrenheit.
Venus is the closest neighbor to the planet, and it takes 224.7 Earth days to orbit the sun.
Earth
The only planet in which there is life, it completes its annual revolution around the sun every 365,256 days.
Its total surface area is 196,940,000 square miles, 71% of which are covered by water, while the remaining 29% are covered by land.
The atmosphere protects life on Earth from uninhabitable outer space, harmful radiation and controls the weather.
Mars
Known as the Red Planet, it has a solid surface just like Earth, but with a thin atmosphere.
Mars is half the size of Earth and is 143,000,000 miles from the sun.
Mars does not have water on its surface due to the low atmospheric pressure.
Buyer
It is the fifth and largest planet in the solar system.
Jupiter has a mass of 2.5 times the total mass of all the other planets combined.
Jupiter is a gaseous planet, which means that it does not have a solid surface, although researchers believe that its core is solid.
Saturn
It is the second largest planet in the solar system after Jupiter.
Just like Jupiter, it is a gaseous planet with nine continuous rings of rock and ice.
Uranus
The third largest planet in Solar SystemIts surface consists of a frozen component, however, its atmosphere is made up of hydrogen and helium along with icy elements such as methane, ammonia, and water.
It is the coldest planet, with a surface temperature of −224 degrees Celsius.
Neptune
The farthest planet from the sun, about 2.8 billion miles from the sun and completing its orbit around the sun every 164.8 Earth years.
It is the windiest planet in the solar system, with an average wind speed of nine times the average wind speed on Earth.
The largest planet in the solar system
Jupiter is the largest planet in the solar system, with an estimated size of about 1,300 times relative to the planet Earth, and among the most important scientific facts associated with Jupiter are the following, that it is a gaseous planet whose outer envelope consists of hydrogen, helium, water droplets, ice crystals and ammonia, in addition to other elements, and its color is A mixture of white, orange, brown and red, an area of about 61.42 billion km, and a mass: 318 times Earth massIts temperature reaches -110 degrees Celsius.
The smallest planet in the solar system
The smallest planet of the solar system is Mercury, with a diameter of about 4,879 km, and a mass of about 3.3010 x 2310 kg. Because of its proximity to the sun, in addition to its small size.
Mercury is one of the four rocky planets, along with Venus, Earth, and Mars, and is characterized by its hard surface full of volcanic craters, and its very thin atmosphere, and it does not have any moons of its own revolving around it.
