Knowledge of the solar system, knowledge about the solar system

Chinese name: solar system.

Product Name: Solar System

Definitions: (1) A system consisting of the Sun and the celestial bodies orbiting around it, and the area of space it occupies. (2) A system of celestial bodies consisting of the Sun, planets and their moons and rings, asteroids, comets, meteoroids and interplanetary matter, and the space areas they occupy.

Disciplines: Astronomy (first-level discipline); Solar System (Secondary Discipline)Solar System**The solar system is the star system we are in now. It is centered on the Sun and is a collection of all celestial bodies that are subject to the gravitational pull of the Sun

Eight planets Pluto have been expelled, at least 165 known moons, and hundreds of millions of small bodies of the solar system. These small bodies include asteroids, Kuiper Belt objects, comets, and interstellar dust. Broadly speaking, the domain of the solar system includes the Sun, 4 inner planets that resemble the Earth, an asteroid belt of many small rocks, 4 huge outer planets filled with gas, and a second small celestial region known as the Kuiper Belt.

Beyond the Kuiper Belt there are ecliptic discrete disks, the heliosphere, and the still hypothetical Oort Cloud.

Please see it in more detail.

The solar system is a group of celestial bodies that attract each other and move together! Her position in the universe is constantly changing!

The Solar System is a system of planets bound together by the Sun's gravitational pull, including 8 planets (from closest to the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune) and at least 173 known moons, 5 identified dwarf planets, hundreds of millions of small solar system bodies, and Halley's Comet.

The solar system is made up of the sun, 8 planets, more than 100 moons, many dwarf planets and countless asteroids, comets, and meteoroids.

The planets are in alphabetical order: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Mercury, Venus, Earth, and Mars, which are close to the Sun, are called terrestrial planets.

Their common characteristics are high density (>, small size, slow rotation, few satellites, mainly silicate (silicate) of internal composition, and a solid shell. Jupiter, Saturn, Uranus, and Neptune, which are far from the Sun, are called Jovian planets.

Their common characteristics are low density (<, large volume, fast rotation, and more satellites. According to spacecraft explorations, it has a thick atmosphere with a solid core similar to that of terrestrial planets.

Yang releases energy in Erg seconds (i.e. 3,860 billion trillion megawatts), which is produced by nuclear fusion reactions. Approximately 700,000,000 tons of hydrogen atoms are converted into approximately 695,000,000 tons of helium atoms per second and 5,000,000 tons (erg) of energy in the form of gamma rays. Because the rays are emitted to the surface of the sphere, the energy is constantly absorbed and dissipated, so that the temperature is constantly lowered, so there is a huge temperature difference between the inside and outside and the basic visible light.

The energy output by convection is at least 20% higher than the energy diverged by radiation.

The outer surface of the Sun is called a photosphere and has a temperature of about 5,800 kilo. Sunspots belong to the "cooler" part of the sun, at only 3800 kai (they look darker because of the comparison to the surrounding area). Sunspots can be very large, up to 50,000 kilometers in diameter.

Sunspots arise as a result of complex and currently unknown interactions from the Sun's magnetic region.

The solar system is a celestial system composed of the sun, planets and their moons, asteroids, comets, meteors, and interplanetary matter, and the sun is the center of the solar system. In the vast family of solar systems, the mass of the sun accounts for the total mass of the solar system, and the nine planets and tens of thousands of asteroids account for a tiny proportion. They orbit the sun for eternity, and at the same time, the sun generously and selflessly dedicates its light and heat to warm every member of the solar system, prompting them to develop and evolve.

In this family, the closest planet to the Sun is Mercury, followed by Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Among them, there are only five that can be seen by the naked eye, for these five stars, different countries have different names, our country has the doctrine of the five elements in ancient times, so it uses the five elements of metal, wood, water, fire, and earth to ...... them respectively

The solar system is a collection of celestial bodies centered on the sun and all celestial bodies constrained by the sun's gravity y there are 7 planets and the earth is a moon and a reference:123 I can't say so much here.
