What are the effects of sunspots on the Earth? How was the Earth born?

The Earth is the third planet from the inner to the outer solar system, and is also the terrestrial planet with the largest diameter, mass, and density in the solar system. The Sun is the source of light and heat on Earth, and its every move will have various effects on the Earth. What are the effects of sunspots on the Earth? Let's open it and learn more.

The impact of sunspots on the Earth

The sun is the source of light and heat on the earth. Its every move will have various effects on the earth. Since sunspots are a kind of intense activity phenomenon of matter on the sun, their impact on the earth is obvious. Sometimes there are some dark areas on the surface of the sun's photosphere. It is the place where the magnetic field gathers. This is the sunspot.

When a large number of sunspots appear on the sun, compasses on Earth will shake and fail to indicate the correct direction. Radio communications will also be severely hampered and may even be suddenly interrupted for a period of time.

Sunspots can also cause climate change on Earth. More than 100 years ago, a Swiss astronomer discovered that when there are many sunspots, the climate on Earth is dry and agricultural harvests are good, while when there are few sunspots, the climate is humid and heavy rains cause disasters.

When the number of sunspots increases, there are more earthquakes on Earth. The number of earthquakes also has a periodicity of about 11 years. The growth of trees also changes with the 11-year cycle of solar activity. Trees grow faster in years with more sunspots, and slower in years with fewer sunspots.

How the Earth was born

The Earth originated from the primordial solar nebula 4.6 billion years ago. The planetesimals that formed the Earth originated from the lumps of gas, ice particles, and dust with a diameter of one to ten kilometers left after accretion collapse. These materials grew for 10 to 20 million years and eventually formed the proto-Earth. The surface of the nascent Earth was an "ocean" composed of magma.

The Earth rotates from west to east and revolves around the Sun. It is now 4.55 billion years old. It originated from the original solar nebula 4.55 billion years ago.

The Earth is the third planet from the inner to the outer solar system. It is also the terrestrial planet with the largest diameter, mass and density in the solar system. It is about 149.6 million kilometers away from the sun.

The interior of the Earth is divided into the core, mantle, and crust structure, and the surface is divided into the hydrosphere, atmosphere, and magnetic field. The Earth is the only celestial body in the universe with known life.

How many kilometers is the space station from the earth?

A space station is a manned spacecraft that operates in low-Earth orbit for a long time and can accommodate multiple astronauts for visits, work and life. Low-Earth orbit refers to an orbit where the spacecraft is relatively low from the ground, generally with an orbit altitude of less than 2,000 kilometers. Space stations operating in low-Earth orbit, such as the Chinese space station, have an orbit altitude of 400-450 kilometers.

The core module of China's space station is named "Tianhe", which is the management and control center of China's space station. It is 16.6 meters long, has a maximum diameter of 4.2 meters, and a launch mass of 22.5 tons. It can support three astronauts to stay in orbit for a long time.

There is still a thin atmosphere in low-Earth orbit. Spacecraft operating there are affected by atmospheric resistance, and their orbits will gradually decay, that is, the orbital altitude will gradually decrease. Therefore, it is necessary to maintain the spacecraft's orbit regularly or irregularly.
