1520970 1 km when the earth is farthest from the sun, and 147098074 km when the earth is closest to the sun. If the average value is taken, it is about1.500 million km.
According to the distance from the sun, the earth is the third closest planet to the sun, and the earth-like planet with the largest diameter, mass and density in the solar system, with a distance of 65.438+0.5 billion kilometers from the sun. The sun is currently passing through the local bubble region of Orion's arm at the inner edge of the Milky Way. There are 50 nearest star systems within 0/7 light-years from Earth/Kloc-.
The distance between the earth and the sun directly determines the biodiversity of various species on the earth and the stable cycle of the ecosystem. If the distance between the earth and the sun changes, the history of the whole earth will be rewritten.
The relationship between the earth and the sun:
The sun is a huge and hot gas planet. If it is too close to the sun, the temperature of the earth will be very high, so the water on the earth will not be preserved because it will evaporate soon. Without water, it is not suitable for human survival. And if it is too far away from the sun, like Uranus and Neptune, the temperature is extremely low and it is not suitable for human habitation.
The earth is in an accurate position that is neither near nor far from the sun, so that life on the earth can flourish. Like the South Pole and the North Pole of the earth, because they are far away from the sun, the time that the sun can shine is very limited, and the environment is harsh, which is not suitable for human survival.
