The maximum distance between the Earth and the Sun is in kilometers, about the beginning of July, and the minimum distance is in kilometers, about the beginning of January. The average distance is kilometers. The distance between the Earth and the Sun is taken as an astronomical unit and rounded up to 150 million kilometers.
This distance is equivalent to 11,700 times the diameter of the Earth, it takes 17 years to reach the Sun by an airplane traveling at 1,000 kilometers per hour, and it takes more than 150 days to launch a spacecraft with kilometers per second, and it takes more than 8 minutes for the sun's rays to reach the Earth.

It is difficult to find out how far the sun is from the earth. I saw a book that said that it took 8 minutes and 20 seconds for the sun to reach the Earth, and the speed of light was 300,000 kilometers per second.
To calculate the distance between the Sun and the Earth, you need to replace 8 minutes and 20 seconds with seconds. One minute is 60 seconds, a total of 8 minutes, and then remove the 0 of 60, and then multiply it by 6 8 48 (seconds). Because 0 is removed after 60, adding 0 after 48 is 480 seconds.
Because it takes 8 minutes and 20 seconds for the sun to reach the earth in front, and 20 seconds need to be added, 480 + 20 = 500 (seconds). 300,000 kilometers per second multiplied by 500 seconds equals 100 million kilometers. 300,000 kilometers seconds 500 seconds = 100 million kilometers, so the sun is 100 million kilometers from the earth.
The average distance of the Earth from the Sun, i.e., astronomical units = this is the exact number seen in a planetarium.

The Sun is about 100 million kilometers away from the Earth. If it is converted to the speed of light, it is about the fraction of light, and if it is forcibly converted into light years, it will be about light years.
We orbit the Sun at a distance of about 150 million kilometers, in fact, since our orbit is an ellipse, this is only an average. At its closest point, the Earth is 147 million kilometers from the Sun, and its farthest distance is 152 million kilometers.
Solar Evolution:
The Sun was formed about 100 million years ago in a cloud of collapsed hydrogen molecules. The time of the Sun's formation is measured in two ways: the Sun's current age in the main sequence zone, confirmed using computer models of stellar evolution and primordial nucleosynthesis, which is about 100 million years old.
This is very consistent with the fact that the oldest material of the Sun is 100 million years old.
The Sun has reached middle age in the evolutionary phase of its main sequence, in which nuclear fusion is the fusion of hydrogen into helium at the core. More than 4 million tonnes of matter are converted into energy at the core of the sun every second, producing neutrinos and solar radiation. At this rate, the Sun has so far converted about 100 Earth-masses of matter into energy, and the total time spent by the Sun in the main sequence is about 10 billion years.

1. The distance between the sun and the earth is light years, because the distance between the sun and the earth is about 100 million kilometers, and the distance of 1 light year is trillions of kilometers.
2. According to the propagation speed of light, it can also be dispersed to calculate the time when sunlight reaches the earth, and it takes about 500 seconds for sunlight to travel to the earth.

The Earth is 100 million kilometers from the Sun. Since the Earth's orbit is an ellipse, this is only an average, and at the nearest place, the Earth is 147 million kilometers from the Sun, and the farthest distance is 152 million kilometers.
The Earth is the third closest planet to the Sun in terms of distance from the Sun, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, at a distance of 100 million kilometers from the Sun.
The sun is a huge and hot planet of gas, and if it is too close to the sun, then the temperature of the earth will be very high, so that the moisture on the earth will not be retained, because it will soon be evaporated, and without water, it will not be suitable for human life.
If it is too far from the sun, like Uranus and Neptune, the temperature is particularly low and unsuitable for human habitation, and the earth happens to be in a position not close to or far from the sun, allowing life on earth to thrive.

The average straight-line distance from the sun to the earth (earth-sun distance) is kilometers, which is by far the most accurate answer.
The eighteenth-century French astronomer Lalande further studied the process of Captain James Cook's observation of the transit of Venus on the island of Tahiti in 1769, and came up with the first data in history that is convenient for reference: 100 million kilometers, which is a very small error from today;
In 1976, the International Astronomical Union set the distance between the Sun and the Earth at 149597870 kilometers in a rigorous scientific spirit, which shows that it is basically consistent with the data of the 21st century.
In 2012, more advanced observation techniques used the transit of Venus to calculate a more accurate distance between the Sun and the Earth, or kilometers, which is a rare and accurate number.
It is an approximate conclusion about the distance between the sun and the earth, but it is also the crystallization of the wisdom of today's scientists, and the measurement of the distance between the sun and the earth is still in progress, and I hope that the day will come when we can get more accurate data.

Average orbital radius: 149,600,000 km (astronomical units from the Sun) Since the Earth's orbit around the Sun is an elliptical and the Sun is at a focal point, this distance varies. Its maximum is 152.1 million km (the Earth is at aphelion); The minimum is 147.1 million km (the Earth is at perihelion); The average is about 149.6 million kilometres; This distance is defined as an astronomical unit, and in 1976 the International Astronomical Union established it as 149597870 km, and has been used since 1984.

Hope to help the landlord. In addition, remind the landlord: it is best to find this kind of problem by yourself in the future, there is it in the encyclopedia, and there is no need to ask questions on knowing. In addition, it is not worth paying bounty points for this. Of course, it is the right of the landlord to do what to do.

Earth-Sun Distance
The distance between the sun and the earth is also known as the distance between the sun. Refers to the length of the straight line from heliocentric to geocentric. Since the Earth's orbit around the Sun is an ellipse and the Sun is at a focal point, this distance varies.
Its maximum is 152.1 million km (the Earth is at aphelion); The minimum is 147.1 million km (the Earth is at perihelion); The average is 149.6 million kilometres; This is an astronomical unit, which was established by the International Astronomical Union in 1976 as 149597870 kilometers and has been in use since 1984. At this distance, it takes only 8 minutes and 18 seconds for sunlight to reach the Earth's surface.

Break away from the inertia of the Earth's rotation and not follow the Earth, so that there can be no day and night, and this has nothing to do with altitude. It has something to do with the gravitational influence of the Earth. >>>More
The sun's luminescence and heat are nuclear fusion, which is a physical reaction, while the combustion phenomenon is a chemical reaction, which is fundamentally different. If the Earth used to be a star, there would be no life now, and to be a star you need to have a large enough mass, which is far from enough for the mass of the Earth. There are generally several outcomes after a star completes the process of the main sequence star, small and medium-mass stars will become black dwarfs or white dwarfs, those with a large mass but not enough to become black holes will become neutron stars, and massive stars that can become black holes will collapse into black holes. >>>More
Yes. The Sun is 1.3 million times larger than the Earth, much larger than the Earth.
It's not that the sun is closest to the earth, but that the earth should be closest to the sun! You made the mistake of geocentrism! >>>More
