How many kilometers is the distance between the Sun and the Earth?

The average distance between the Sun and the Earth is about 100 million kilometers. The exact distance is 149597870 km.

The distance between the Sun and the Earth is not fixed, but sometimes far and near. At its farthest from the Sun, the distance is 152.1 million kilometres (the Earth is at aphelion.

The minimum is 147.1 million km (the Earth is at perihelion); Average value.

149.6 million kilometres. This average is an astronomical unit.

The average distance between the Sun and the Earth is 100 million kilometers. Since the Earth's orbit is not a perfect circle, the distance between the Sun and the Earth will vary to a certain extent, but this change is relatively small compared to the distance between the Sun and the Earth.

The distance from the Earth to the Sun at perihelion is about 100 million kilometers. The Earth is about 100 million kilometers away from the Sun at aphelion.

The Earth's orbit around the Sun is an ellipse and the Sun is located at a focal point, so the distance between the Earth and the Sun varies from moment to moment: the maximum is 152.1 million km (aphelion); The minimum is 147.1 million km (perihelion); The average is 149.6 million kilometres.

Isn't the sun to the earth the season he calculates according to the kilometer of the speed of light in the head of the junior high school science textbook.

The average distance from the Earth to the Sun is 100 million kilometers, and 1 light-year is about 9.46 trillion kilometers. Except for it, it's light years!

Sun-Earth distance, also known as solar distance, refers to the length of a straight line from the center of the sun to the center of the earth. Since the Earth's orbit around the Sun is an ellipse and the Sun is at a focal point, this distance changes from time to time. Its length is about 149597870 kilometers.

The distance between the Sun and the Earth, in turn, is an astronomical unit of length, which was once defined by the average distance between the Earth and the Sun, but has now been changed to an absolute distance of 149,597,870,700 meters. Astronomically, this length is determined to be 1AU, i.e. an astronomical unit.

Hello classmate, the average distance between the earth and the sun is 100 million kilometers, and the speed of light is 300,000 kilometers per second, so it takes 8 minutes and 19 seconds for the light emitted by the sun to reach the earth, that is, the sunlight (sunlight) we see is emitted from the sun 8 minutes and 19 seconds ago.

Hope it helps.

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 above data are modern measurements, and have been tested countless times before, and the following is a summary of the important results of the long history of measuring the distance between the Sun and the Earth, and some of the measured data:

In ancient Greece, the concept of the distance between the sun and the earth already existed, and some scholars measured the length of the sun and the moon by visual inspection.

In the 18th century, the 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 of 10 kilometers from today.

The average distance between the Sun and the Earth is an astronomical unit (AU). Because that's the definition of an astronomical unit itself.

The astronomical unit (abbreviated as au) is a unit of length that is historically approximately equal to the average distance between the Earth and the Sun. One of the astronomical constants.

The basic unit for measuring distances in astronomy, especially between celestial bodies within the solar system, the average distance from the Earth to the Sun is one astronomical unit. The unit of astrology is about 100 million kilometers.

The distance from the sun to the earth was determined by the International Astronomical Union in 1976 to be 149597870 kilometers, or 149597870 kilometers, and used as an astronomical unit to measure distance.

The Earth does not revolve around the Sun in a perfect circular orbit, so the Sun-Earth distance is not a constant. However, the Earth's orbit is an elliptical with a very low eccentricity, close to circular. The average distance between the Sun and Earth is about 100 million kilometers, and if you have to express it in light years, you need to know the definition of light years.

The propagation velocity of light in a vacuum is a constant, independent of the choice of reference frame, and its value is constant at 299792458 meter second. Then multiply the speed of light by the time of a year, and this is the distance that light travels in a year, which is 1 light year, which is about a trillion kilometers in size. Thus, the average distance between the Sun and Earth is expressed as a light-year, or light-year.

That's about 100 million kilometers! That is, 150000000kmIt's not light years!

If it is said in detail.

The Earth's orbit around the Sun is a nearly circular ellipse, and the Sun is located at a focal point of the elliptical orbit, so that the distance between the Sun and the Earth is constantly changing over the course of a year or even a day.

At the beginning of January every year, the Earth is at the perihelion of its orbit around the Sun, and the distance between the Sun and the Earth reaches a minimum value, which is about 100 million kilometers.

At the beginning of July every year, the Earth is located at the aphelion point of its orbit around the Sun, and the distance between the Sun and the Earth reaches its maximum value, which is about 100 million kilometers.

An average of 100 million kilometers.

Average distance between the Sun and Earth (in 1 day): meters (150,000,000 km) The farthest distance between the Sun and Earth: meters.

Closest distance between Sun and Earth: m.

The difference between aphelion and perihelion is 5 million kilometers.

Earth is one of the eight planets in the solar system, the third planet in order from near to far, 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. The Earth rotates from west to east while revolving around the Sun.

How far is the Earth from the Sun? Speak out and scare you!

The average distance from the Sun to the Earth is 100 million kilometers.

I don't know why it's so fast for an hour.

The average distance of the Earth from the Sun (i.e. one astronomical unit): 149 598 020 km

Maximum distance between the Sun and Earth (2 July): 152 100 000 km

Closest distance between the Sun and Earth (2 January): 147 100 000 km
