- this is 8 planets and more than 63 of their satellite, which are opened more often, several dozen comets and a large number of asteroids. All cosmic bodies move along their clear directed trajectories around the Sun, which is 1000 times heavier than all the bodies in the solar system combined
SUN-It is a star without which there could not exist life on Earth. It gives us energy and warmth. According to the classification of stars, the Sun is a yellow dwarf. The age is about 5 billion years. It has a diameter on the equator equal to 1,392,000 km, 109 times greater than the earths. The period of rotation at the equator is 25.4 days and 34 days at the poles. The Suns mass is 2х10 to 27 degrees, approximately 332950 times the mass of the Earth. The temperature inside the core is about 15 million degrees Celsius. The temperature on the surface is about 5500 degrees Celsius. According to the chemical composition, the Sun consists of 75% hydrogen, and 25% of the others are helium. Now, in order to understand how many planets around the sun rotate, in the solar system and the characteristics of the planets.
1. "Mercury" Four inner planets (nearest to the Sun) - Mercury, Venus, Earth and Mars - have a solid surface. They are smaller than the four giant planets. Mercury moves faster than other planets, firing in the sunlight during the day and freezing at night.2. "Venus" is more like the Earth in size and brightness. Observation of it is difficult because of the clouds enveloping it. The surface is a hot stony desert.3. "Earth" Apparently, the Earth was formed from a gas-dust cloud, like other planets. Particles of gas and dust colliding, gradually "raised" the planet. The surface temperature reached 5000 degrees Celsius. Then the Earth cooled and was covered with a hard stone bark. But the temperature in the bowels to this day is quite high - 4500 degrees. The rocks in the bowels are melted and when they erupt volcanoes pour out onto the surface. Only on earth there is water. Therefore, there is life. It is located relatively close to the Sun in order to receive the necessary heat and light, but far enough not to burn.4. "Mars" Because of the similarity with the Earth, it was believed that there is life. But the spacecraft that descended to the surface of Mars did not find any signs of life. This is the fourth largest planet.5. "Jupiter" Jupiter, Saturn, Uranus and Neptune consist of hydrogen and other gases. Jupiter exceeds the Earth more than 10 times in diameter, 300 times in mass and 1,300 times in volume. It is more than twice as massive as all the planets of the solar system combined. How much planet does Jupiter need to become a star? We need to increase its mass by 75 times!6. "Saturn" 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.7. "Uranus" The unique planet of the solar system. Its feature is that it rotates around the Sun not like everyone, but "lying on its side." Uranium also has rings, although they are harder to see. In 1986, "Voyager -2" flew at a distance of 64 000 km, he had six hours for photography, which he successfully implemented.8. "Neptune" At the moment, Neptune is considered the last planet of the solar system. His discovery occurred as a method of mathematical calculations, and then he was already seen through a telescope. In 1989, the Voyager 2 flew by. He made astounding photographs of the blue surface of Neptune and his biggest satellite Triton.
