How many planets in the solar system in order with a photo

The solar system consists of eight planets and more than 63 of their satellites, which are opened more and more often, as well as several dozen comets and a large number of asteroids. All cosmic bodies move in their clear directional trajectories around the Sun, which is 1000 times heavier than all the bodies in the Solar System combined.

How many planets around the sun rotates

How did the planets of the solar system: approximately 5-6 billion years ago, one of the gas and dust clouds of our large galaxy (the Milky Way), having a disk shape, began to shrink to the center, gradually forming the present Sun. Further, according to one of the theories, under the action of powerful forces of attraction, a large number of dust and gas particles orbiting the Sun began to stick together into balls - forming future planets. As another theory says, the gas-dust cloud immediately disintegrated into separate clusters of particles, which, compressed and compacted, forming the current planets. Now 8 planets around the Sun rotate constantly.

The center of the solar system is the Sun - a star around which planets orbit. They do not emit heat and do not shine, but only reflect the light of the sun. In the solar system, 8 planets are now officially recognized. Briefly, in order of distance from the sun, we list them all. And now a few definitions.

The satellites of the planets. The solar system also includes the Moon and the natural satellites of other planets that all of them have, except Mercury and Venus. Over 60 satellites are known. Most of the satellites of the outer planets discovered when they received photographs taken by automatic spacecraft. The smallest satellite of Jupiter - Leda - just 10 km across.

The sun is a star, without which life could not exist on Earth. It gives us energy and warmth. According to the classification of stars, the Sun is a yellow dwarf. The age of about 5 billion years. It has a diameter at the equator of 1,392,000 km, 109 times the size of the earth. The rotation period at the equator is 25.4 days and 34 days at the poles. The mass of the Sun 2x10 in 27 degree tons, about 332950 times the mass of the Earth. The temperature inside the core is about 15 million degrees Celsius. The surface temperature is about 5500 degrees Celsius.

By chemical composition, the Sun consists of 75% of hydrogen, and of the other 25% of elements, most of it is helium. Now, in order, let us examine how many planets around the sun rotates, in the solar system and the characteristics of the planets.

Atmosphere: very rarefied, helium.

How many satellites: 0.

The main satellites of the planet: 0.

Venus - 2 in order planet of the solar system

Venus is more like Earth in size and brightness. Observation of it is difficult because of the clouds enveloping it. The surface is hot stony desert.

Characteristic of the planet Venus:

Diameter at the equator: 12104 km.

Period of rotation (rotation around the axis): 243 days.

Surface temperature: 480 degrees (average).

Atmosphere: dense, mostly carbon dioxide.

How many satellites: 0.

The main satellites of the planet: 0.

Earth - 3 in order planet of the solar system

Apparently, the Earth was formed from a gas and dust cloud, like other planets in the solar system. Particles of gas and dust colliding, gradually "raised" the planet. The surface temperature reached 5,000 degrees Celsius. Then the Earth cooled and covered with hard stone bark. But the temperature in the depths to this day is quite high - 4500 degrees. Rocks in the depths of the melted and during the eruption of volcanoes poured to the surface. Only on earth there is water. Therefore, there is life. It is located relatively close to the Sun to receive the necessary heat and light, but far enough so as not to burn.

Characteristics of planet Earth:

The period of revolution around the Sun: 365.3 days.

Diameter at the equator: 12756 km.

The period of rotation of the planet (rotation around the axis): 23 hours 56 minutes.

Surface temperature: 22 degrees (average).

Atmosphere: mainly nitrogen and oxygen.

Number of satellites: 1.

The main satellites of the planet: the moon.

Mars - 4 in order planet of the solar system

Because of the similarity with the Earth, it was believed that life exists here. But the spacecraft that landed on the surface of Mars did not detect any signs of life. This is the fourth order of the planet.

Characteristic of the planet Mars:

Period of revolution around the Sun: 687 days.

The diameter of the planet at the equator: 6794 km.

Rotation period (rotation around the axis): 24 hours 37 minutes.

Surface temperature: -23 degrees (average).

The atmosphere of the planet: rarefied, mostly carbon dioxide.

How many satellites: 2.

The main satellites in order: Phobos, Deimos.

Jupiter - 5 in order planet of the solar system

Jupiter, Saturn, Uranus and Neptune are composed of hydrogen and other gases. Jupiter exceeds Earth by more than 10 times in diameter, 300 times in weight and 1300 times in volume. It is more than twice as massive as all the planets of the solar system combined. How many planets does Jupiter need to become a star? It is necessary to increase its mass 75 times!

Characteristics of the planet Jupiter:

Period of revolution around the Sun: 11 years 314 days.

The diameter of the planet at the equator: 143884 km.

Rotation period (rotation around the axis): 9 hours 55 minutes.

Atmosphere: mostly hydrogen and helium.

Number of satellites: 16 (+ rings).

The main satellites of the planets in order: Io, Europe, Ganymede, Callisto.

Saturn - 6 in order planet of the solar system

This is number 2, the largest of the planets of the solar system. Saturn attracts the eye due to the system of rings, formed from ice, stones and dust, which revolve around the planet. There are three main rings with an external diameter of 270000 km, but their thickness is about 30 meters.

Characteristics of the planet Saturn:

How many planets in the solar system: 8 or 9?

Earlier, for many years, astronomers recognized the presence of 9 planets, that is, Pluto was also considered to be a planet, like the rest of the already known ones. But in the 21st century, scientists were able to prove that it is not a planet at all, which means that there are 8 planets in the solar system.

Now, if you are asked how many planets in the solar system, answer boldly - 8 planets in our system. It has been officially recognized since 2006. When building the planets of the Solar System in order from the sun, use the finished picture.
