What is the universe we see? Here we can assume that it is a certain organism's cell, and these cells happen to form elements of the universe and form the body of this organism. However, under these cells, there are more quantum units, so how big are the elements of the universe? Let's take a look at these stars together.
1, Ceres
It is the smallest planet in the solar system and the only dwarf planet with an asteroid belt , with a diameter of about 950 kilometers. There are a lot of ice-water substances on the surface and a lot of water-carrying minerals. However, astronomers have also explored that there are water vapors on Ceres. These water vapors come from the darker areas on the surface of Ceres, and the amount of water vapor is not large, about 6 kilograms per second. This discovery, researchers speculated that the ocean with liquid water may have a sea of liquid water. Whenever the sky is dark enough, Ceres can be seen with binoculars.
2. Moon
It is a celestial body that orbits the earth and is also the only natural satellite on earth. It has a diameter of about 3500 kilometers and is more than 384,400 kilometers away from the earth, which is about 30 times that of the earth. There are many sinkholes on the surface of the moon, which may be craters hit by small celestial bodies, forming "html January sea ". The moon we see is all glowing, but in fact the moon itself does not glow. It just emits sunlight and shines on the earth. There is no atmosphere on the moon, and the temperature is also very low during day and night, and there are also layered tissues such as crust, mantle, and nuclear bomb on it.
3, Iobo
0 The third largest satellite in the solar system, , is a satellite orbiting Jupiter , and is also the second largest satellite of Jupiter. It is also the brightest one of Jupiter, with a diameter of about 4,800 kilometers. Made of rocks and water, astronomers have discovered that its surface contains various organic substances such as ice, carbon dioxide , silicate , and underground seas formed by liquid water are also present under the surface, and there are also many impact craters, with uneven surfaces. It is the best object used by astronomers to refer to and study.
4. Mercury
It is the smallest of the eight planets and is also the closest planet to the sun, with a diameter of about 4,900 kilometers. There is no atmosphere on the surface of Mercury to regulate heat, so it is the planet with the largest temperature difference between day and night in the solar system. Because it is too close to the sun, it has two temperature differences relative to it. One faces the sun, and the other is quite high in the temperature difference between the sun, and the other is quite low in the sun, and its revolution speed is far greater than that of other planets. The only similarity between Mercury and the moon is that they have craters and impact craters on the surface, which are also composed of a mantle, a crust and three layers. Except for the earth, Mercury has the largest density. Because Mercury is small, it is difficult for people to see it.
5. Mars
The planet in the solar system is most like the earth, with a diameter of about 6,800 kilometers. Its rotation period is almost the same as that of the earth, and is called the "red planet". The orange-red surface is covered by hematite , mainly based on carbon dioxide, which is both thin and cold, covered with impact craters, canyons, sand dunes and gravel , and there is no stable liquid water. Its environment is dry, similar to the desert on the earth. The only difference is that it is low temperature and lacks plate movement.
6. Venus
A planet that is almost the same size as the earth is one of the eight major planets. At the same time, the planet closest to the earth has a diameter of about 12,000 kilometers, and is covered with thick clouds like the earth. The surface atmospheric pressure is 90 times that of the Earth's sea level, and its temperature can reach 475 degrees Celsius. Its ground surface is very flat, and compared with the moon and Mercury, it has few impact craters.
7. Earth
The planet on which our humans and other organisms rely on is the only celestial body with a living existence so far, with a diameter of about 13,000 kilometers. It is a blue water ball with an elliptical shape and its surface covers more than 70% of the sea water. All material indicators on the earth are met, and they are most suitable for human survival in terms of temperature and terrain, and are not available on other planets.
Editor believes that:
Universe is like cell network. These planets are cells, and each universe is composed of multiple elements with a larger scale. These planets often form behemoths that we cannot imagine. However, the so-called Big Bang may just be the moment when the fertilized egg of a giant creature is formed. As the giant creature embryo grows, from growth to old age to death.
