Tell Me Why
Is the Earth Always at the Same Distance from the Sun?The following question may come to your mind:
Why is the weather hot in summer and cold in winter?
Here is the answer:
The reason for this goes back to the position of the Earth’s axis and its rotation around the sun. This change is considered slight, if we take into consideration the great distance between the sun and the Earth.
This slight change is what makes us feel heat in summer and cold in winter.
You can imagine what life would be like if the distance between the Earth and the sun changed even by a small amount. It would certainly become impossible. If we came closer, we would burn from its heat, and if we moved farther away, the cold would stop life. Without doubt, the distance between the Earth and the sun remains at one fixed distance at all times, and the distance is, in numbers, 93 million miles. Therefore, the rotation of the planets around the sun is what leads to this change, especially the rotation of the Earth. Some of these planets may have orbits that are not completely circular.
Therefore, the distance between the sun and the Earth changes during the year.
The planet Pluto, for example, is the farthest planet from the sun, and its inclination differs from the orbit of the rest of the other planets. It moves away from the circular shape.
The distance of the planet Venus from the sun ranges from 67 million to 68 million miles, and it comes directly after Earth in its distance from the sun. Its average journey is about 67,700,000, sixty-seven million and seven hundred thousand miles.
Then comes the planet Jupiter in its distance from the sun, and its distance is greater than the distance of Mars.
Thus, through our study of the distance between the Earth and the sun, we find that each planet has a special distance and a certain range that helps in the effect of the sun on it, especially our planet Earth. The reason for the changes is the gravitational force of each planet from the other planets in our solar system.
