How far is the earth from the sun?
Unit: km

The sun is 150 million kilometers away from the earth!
It's very difficult to find out how far the sun is from the earth. I read a Book: it says that it takes 8 minutes and 20 seconds for the sun to shine on the earth, and the speed of light reaches 300000 kilometers per second. To calculate the distance between the sun and the earth, we need to first change 8 minutes and 20 seconds into seconds. One minute is 60 seconds, and there are 8 minutes in total. Then remove the zero of 60, and multiply it by 6 × 8 = 48 (seconds), So adding 0 after 48 is 480 seconds. Because it takes 8 minutes and 20 seconds for the sun to shine on the earth in front of it, and it also needs 20 seconds, 480 + 20 = 500 (seconds). 300000 kilometers per second multiplied by 500 seconds equals 150 million kilometers. 300000 kilometers / second × 500 seconds = 150 million kilometers, so the sun is 150 million kilometers away from the earth
The average distance between the earth and the sun is 1.4959787e11m
This is the exact figure seen in the planetarium

How far is the earth from the sun?

The earth's orbit around the sun is an ellipse which is close to a circle. The sun is located at a focal point of the ellipse, so the distance between the sun and the earth is constantly changing in a year or even in a day
