All the planets in the solar system are not as large as the Sun in terms of mass and volume combined

Far from the solar system.

In the solar mass, the mass accounts for almost, other planets plus their moons, as well as the asteroid comet, the Kuiper belt.

Small celestial bodies, gravel, etc., all known masses and only occupy! Although there is not such a big difference in volume, the sun is also the absolute hegemon.

I can carry it a little, but only in %.

It is also relatively normal for a galaxy to have two stars, such as Sirius A and its companion star Sirius B, but Sirius B has already taken the lead, and the current stage of development is already one of the corpses of the star, the white dwarf! This means that billions of years ago, it was also a star that illuminated the universe (and of course white dwarfs shine the same now, but from a small sun to a small candle)!

The solar system coincidentally formed 8 planets, and if all the planets except the sun converged into a single celestial body, would it be possible to form stars? This may seem like a problem, but it's not that hard to figure out, just calculate the mass of the other celestial bodies except the Sun! Of course, there is another way that does not need to be calculated at all, let's understand the proportion of the sun's matter in the solar system!

1.The Sun accounts for the mass of all the material in the solar system!

2.Jupiter is twice the mass of the other planets combined!

3.It takes 13 times the mass of Jupiter to form a brown dwarf!

4.It takes at least 80 times the mass of Jupiter to form a red dwarf!

5.Jupiter has about one thousandth the mass of the Sun!

There are these five to figure out this problem, to achieve the minimum standard of the star needs 8% of the mass of the sun (of course, not only mass, but also a large amount of hydrogen, this does not need to worry, Jupiter, Saturn, Uranus, Neptune, etc. are all celestial bodies with a large amount of hydrogen, so the key is to make up enough mass, as long as the mass is reached, hydrogen can become the sun even if the proportion is slightly smaller!). But it's a pity that the sum of other materials in the solar system is only that of the sun, and even the very low standard of the solar mass of brown dwarfs cannot be reached!

Then I'm sorry, there is not much material in the solar system, the sun is the only one, and it was swallowed by it, leaving a little scum to form a few planets, just enough for life to develop, this alone is enough to laugh at the Sirius galaxy, you have two stars that are considered hairy, and it is not a barren land?

So to sum up, the mass of all the planets in the solar system combined is not as large as the mass of the sun.

How many planets are there in the solar system? Which one is the most massive? The solar system has eight planets, including Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

The first four belong to terrestrial planets, which are small in size and high in density, and are solid, while the last four belong to wood-like planets, which are large in size, low in density, and in a gaseous state. Based on the farthest orbital radius of Neptune, the eight planets and the Sun are distributed within a near-circular radius of about 30 astronomical units.

Earth is the planet where humans live, and every attribute appears in the introduction of other planets. Mars Mars has a radius of 3,400 kilometers and a mass of 11% of Earth, which cannot be compared in volume and mass with Earth, but Mars has had Earth's current climate for billions of years. Maybe there was already life on Mars by then.

However, as the temperature of the Martian inner core continues to drop, the magnetic field gradually disappears, the solar wind can invade unscrupulously, and the gravity itself is not strong enough, the liquid water and atmosphere on the surface of Mars gradually disappear, and finally has today's desolate appearance. But if one day humanity will establish colonies on outer planets, Mars will still be the first choice among the eight planets.

Mercury Mercury is the closest planet to the Sun, with an average orbital radius of about astronomical units (the length of an astronomical unit is the average distance from the Earth to the Sun), and its body size is also smaller than that of Earth, with a radius of 2,440 kilometers and a mass of only Earth. So the gravity on the surface of Mercury is only 40% of that of Earth. The rotation period of Mercury is only the orbital period and 3:

2。That is, when it rotates three times, it makes two revolutions around the sun.

Venus Venus is very similar to the mass, volume and density of our Earth, first of all, Venus has a radius of about 6000 km (the radius of the Earth is 6371 km), and the mass of Venus is about 500 million kg (85% of the mass of the Earth), so the average density of Venus is 5200 kg cubic meters (the average density of the Earth is 5500) but the direction of rotation of Venus is the most special of the eight planets (the second is Uranus). The direction of rotation is opposite to the direction of air combat, the rotation period is 243 days, and the revolution period is days. That is, the rotation is slower than the revolution.

In addition, the surface environment of Venus is also very harsh, and the atmosphere rich in dense greenhouse gases makes the greenhouse effect of Venus very strong, with a surface temperature close to 500 degrees Celsius.

The eight planets are the eight large planets of the solar system, and they are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune in descending order from near to far. Among them, Jupiter is the most massive of the planets in the solar system, its mass is more than 300 times that of the Earth, and its volume is more than 1,300 times that of the Earth. Known as the "King of the Planets".

Jupiter is the planet with the most natural satellites in the solar system, with as many as 66 moons.

Now there are eight planets, which are Venus, Jupiter, Uranus, Neptune, Mars, Mercury, Earth, and Saturn. The most massive is Jupiter, a gas giant.

There are a total of 8 planets in the solar system, and the most massive planet is Jupiter, which is the fifth planet from the Sun. Its mass is 27 kilograms.

There are eight planets, and the most massive planet is Jupiter, which is also the largest in size. This is one of the most unique planets, and the planetary belt next to it is also the largest.

1. Mercury: mass kilograms.

Mercury is the closest to the Sun and is the second asteroid in the solar system. Mercury is smaller in diameter than Ganymede and Titan, but it is heavier.

2. Venus: mass kilograms.

Venus is one of the eight planets in the solar system, and is the second planet in descending order from closest to the sun. It is the closest planet to Earth (Mars is sometimes closer). The orbital period is Earth Day.

3. Earth: mass kilograms.

Earth is one of the eight planets in the solar system, the third in order of near and far from the sun, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, 100 million kilometers away from the sun.

4. Mars: mass kilograms.

Mars is one of the eight planets in the solar system, the fourth planet in the solar system from the inside to the outside, and is a terrestrial planet, with a diameter of about 53% of the Earth and a mass of 11% of the Earth. The inclination angle of the axis of rotation and the rotation period are similar to those of the earth, and one revolution is about twice the time of the earth's revolution.

5. Jupiter: Mass kilograms.

Jupiter is the largest and fastest-rotating planet among the eight planets in the solar system, the fifth planet from the inside out. It has a mass of one-thousandth the mass of the Sun and a mass of the other seven planets in the Solar System combined.

6. Saturn: mass kilograms.

Saturn, one of the eight planets in the solar system, is the 6th closest to the Sun (from near to far). mass, second only to Jupiter in diameter. and Jupiter, the same gas giant. In ancient Europe (ancient Greece), Saturn was called Cronos, and in ancient China, it was also called Zhenxing or Filling.

7. Uranus: mass 13 10 kg.

Uranus is the seventh planet (astronomical unit) in the solar system from the inside out, the third largest planet in the solar system (larger than Neptune) and the fourth most massive (smaller than Neptune), lying almost horizontally orbiting the Sun.

8. Neptune: Mass kilogram (17 times the mass of the Earth).

Neptune is the far-reaching planet of the eight planets, and Neptune is the eighth planet in terms of planet distance from the Sun, the fourth largest planet in diameter, and the third largest planet in mass. Its brightness is only equal and can only be seen in astronomical telescopes.

The most massive planets in the solar system are as follows:Of the eight planets, the most massive is Jupiter.

The eight planets are arranged in order of mass, from largest to smallest: Jupiter, Saturn, Neptune, Uranus, Earth, Venus, Mars, and Mercury.

The eight planets are the eight large planets of the solar system, according to the distance from the sun from near to far, they are Mercury ( ) Venus ( ) Earth ( ) Mars ( ) Jupiter ( ) Saturn ( ) Uranus ( ) Neptune ( ) Most of the eight planets have the same rotation direction as the direction of revolution. There are only two exceptions: Venus and Uranus. Venus rolls in the opposite direction of rotation to the direction of revolution.

Mercury: Mercury is the closest to the Sun and is the second asteroid in the solar system. Mass e23 kg.

Venus: Venus is the second closest planet to the Sun and the sixth largest planet in the solar system. Mass e24 kg.

Earth: Earth is the third and fifth largest planet from the Sun; Mass e24 kg. Mars:

Mars is the fourth farthest from the Sun and the seventh largest planet in the Solar System. Mass e23 kg. Jupiter: Jupiter is the fifth planet from the Sun; Mass e27 kg.

Saturn: Saturn is the sixth-farthest planet from the Sun and the second-largest of the eight planets; Mass e26 kg. Uranus:

Uranus is the seventh farthest planet from the Sun in the Solar System; Dressing weight e25 kg. Neptune: Neptune is the eighth planet orbiting the Sun; Mass e26 kg.

Jupiter's mass is twice the mass of the other seven planets in the solar system combined, 318 times that of Earth, and 1,321 times the volume of Earth. It is the fifth-closest planet to the Sun in the Solar System and the largest in the Solar System. Like other giant planets, Jupiter does not have a solid surface, but is covered with clouds 966 kilometers thick.

Viewed through a telescope, these clouds resemble ribbons of color on Jupiter.

Jupiter. The order of mass of the eight planets of the solar system from largest to smallest is: Jupiter, Saturn, Neptune, Uranus, Earth, Venus, Mars, and Mercury.

The solar system is a system of celestial bodies centered on the Sun and bound together by the Sun's gravitational pull, including the Sun, planets and their moons, dwarf planets, asteroids, comets, and interplanetary matter. As of October 2019, the solar system includes the Sun, 8 planets, nearly 500 moons, and at least 1.2 million asteroids, as well as a number of dwarf planets and comets.

Sedna is the largest known asteroid in our solar system, with a diameter of about 1,600 kilometers, an elliptical orbit, and a maximum distance of 80 AU from the Sun, and a maximum distance of 500 AU, orbiting the Sun for 10,000 years.
