The distance between the Earth and the Sun is approx

Date:

What is the distance between earth and sun? Sun is the central star in our solar system. All the celestial bodies revolve around it at different distances and the astronomical unit scale is used to determine the distance between the sun and the celestial bodies. On the Contents page, we will explain how far is the distance between the Earth and the Sun? Is the distance between the Earth and the Sun constant? throughout the year.

The distance between the Earth and the Sun is approx

Distance between Earth and Sun It will be approx 150 million kilometers or about 1.58125 x 10^5 light yearsIt is equal to one astronomical unit. In particular, scientists have been interested in measuring the distance between the Earth and the Sun for ages. The first attempt was made by the Greek scholar Aristarchus in 250 BC. He relied on measuring the mass of the Moon based on the distance between the Earth and the Sun. Scientists, especially astronomers, relied on its measurement until the last century.

Information about the distance between the Earth and the Sun

Knowing the distance between the Earth and the Sun, below are several brief information about the distance between these two bodies:

  • As sunlight travels at a speed of 300,000 kilometers per second, it takes 8 minutes to reach the earth.
  • With the development of technological science, spacecraft and advanced radar devices, the distance between the Sun and the Earth can be directly and easily measured after the old method of measurement relied on lunar measurements.
  • After changing the value of the astronomical unit, the measurement was based on the change in mass of the Sun as it emitted energy.
  • In 2012, the International Astronomical Union voted to change the definition of an astronomical unit to 149,598,428 km. It is based on a number of data, including: measuring the speed of light and constant distance without taking into account the mass of the Sun.

Is the distance between the Earth and the Sun constant?

The Earth moves in an elliptical path around the Sun, so the distance between the Earth and the Sun varies. It also changes during the year according to the season. The closest of these distances is 147.1 million kilometers. The longest of these distances is 152.1 million kilometers. Earth is closest to the Sun in the Northern Hemisphere during winter.

So we clarified The distance between the Earth and the Sun is approx At any point between 147 and 152 million kilometers, this distance is constantly changing as the Earth orbits itself and the Sun in an elliptical orbit. This explains the difference in distance between summer and winter.
