Who knows how far the sun is from the earth?


The earth's orbit around the sun is an elliptical curve with a length of 934 million kilometers. It takes 365 days, 5:48:46 seconds for the earth to revolve around the sun, so its common angular velocity is about 1 ° every day. The distance between the earth and the sun varies with the position of the earth in the orbit. The farthest time from the sun is about July 4 every year



How far is the earth from the sun


At the beginning of January every year, the earth is located at the perihelion of the orbit around the sun, and the distance between the sun and the earth reaches the minimum value, about 147.1 million kilometers. At the beginning of July every year, the earth is located at the aphelion of the orbit around the sun, and the distance between the sun and the earth reaches the maximum value, about 152.1 million kilometers



How far is the sun from the earth? How long does light travel?


The earth's orbit around the sun is a nearly round ellipse, and the sun is located at a focal point of the ellipse orbit. In this way, the distance between the sun and the earth is constantly changing in a year or even in a day
At the beginning of January every year, the earth is at the perihelion of the orbit around the sun, and the distance between the sun and the earth reaches the minimum value, about 147.1 million kilometers
At the beginning of July every year, the earth is located at the apogee of the orbit around the sun, and the distance between the sun and the earth reaches the maximum, about 152.1 million kilometers
[distance between the sun and the earth]
The maximum distance between the earth and the sun is 1.521 × 108km, about at the beginning of July every year, and the minimum distance is 1.471 × 108km, about at the beginning of January every year. The average distance is 1.496 × 108km. People regard the distance between the earth and the sun as an astronomical unit, and take its integer as 150 million km. This distance is equivalent to 11700 times the diameter of the earth, It takes 17 years to get to the sun by a plane with a speed of 1000 kilometers per hour, and it takes more than 150 days to launch a spacecraft with a speed of 11.23 kilometers per second. It takes more than 8 minutes for the sun to shine on the earth
