For all those interested in astronomy, as well as students who study the planets, stars, and the movement of the solar system, the subject of the Earth’s rotation around the sun is one of the main topics that attracts attention and calls for many discussions and readings for knowledge, understanding, and study.
In this article, we discuss the subject of the Earth’s rotation around the sun and the four seasons in a simple and detailed manner, full of interesting and surprising information.

Earth’s rotation
The Earth remains in a state of rotation around itself, as well as around the Sun, in a smooth and regular rotation that carries many secrets and information that are interconnected with each other to provide a good explanation of the occurrence of what is called day and night.
As well as occurrence the four Seasonsclimate changes and temperature differences from place to place, dividing the globe between a dark part that lives at night and a light part that lives during the day, and then the roles are exchanged.
This is what happens with the northern and southern hemispheres in the four seasons between winter, summer, spring, and fall, and these are the things that we try to understand by understanding the Earth’s rotation.

The Earth’s rotation around itself
The Earth rotates around itself once every 24 hours, which we know as the Earth’s day. The Earth rotates around its axis due to central gravity at a regular speed from west to east.
This makes the eastern parts precede the western parts in time, so they are closer to the sun, which results in a difference Timing From place to place on planet Earth, the parts closest to the east are ahead in time.
Thus, the Earth is divided into a group of longitude lines of up to 360 longitude lines, each line separated from the other by 4 minutes in time. If we calculate each line by 4 minutes, we arrive at the number of minutes that represents 24 hours, which is the period during which the Earth rotates around itself in a complete revolution. .

Earth’s rotation around the sun
The Earth also revolves around the Sun once every 365 days and a quarter, which is known as the solar year or the Earth year.
The Earth rotates in a fixed orbit around the sun called the Earth’s orbit, which causes the four seasons that we know on planet Earth to occur, due to the tilt of the Earth’s axis by 23.5 degrees.
This makes the northern hemisphere tend toward the sun in the northern summer and southern winter, while the southern hemisphere tilts toward the sun in the southern summer and northern winter.
The two hemispheres are at the same distance from the sun in the spring and fall seasons, which is known as the equinoxes, so the Earth is in a middle position in front of the sun.

Information about the Earth’s rotation around the sun
The Earth’s rotation around the Sun occurs due to the mass of the Sun, which is 300,000 times the mass of the Earth, which causes a great gravitational pull towards the Sun, and this has a role in creating a constant movement from the Earth’s rotation around the Sun, which is known as the annual cycle.
The planets of the solar system also revolve around the sun in fixed orbits that do not intersect with each other, and do not precede one another. Likewise, the sun rotates and moves in its own path, which is estimated at billions of miles.
In the past, scientists believed that the sun revolves around the Earth, which was announced by Ptolemy in his theory that presents a model of geocentrism, but Nicolaus Copernicus had an important theory that spoke of heliocentrism in the second century, which was scientifically proven later with the development of measuring and observing tools. .
The sun is the main factor of life on a planet the earth Which provides it with light and heat, and the distance between the sun and the Earth completely allows for living on planet Earth.
Being close to the sun means the surface of the Earth is hot, and being away from the sun means cold and freezing. In both cases, life becomes impossible on planet Earth.
For Earth, it is the fifth largest planet in the solar system, and it is also the third planet in distance from the Sun.
Our planet is characterized by the presence of oxygen, gravity, and water, in addition to the appropriate distance between it and the sun, which makes planet Earth viable for human life, which is not available to the rest of the planets in the solar system.
As a result of the relationship between the sun, the Earth, and the moon, a phenomenon called a lunar eclipse and another phenomenon called a solar eclipse also occur
The phenomenon of a lunar eclipse occurs when the Earth is located between the Sun and the Moon, so the sun’s rays do not reach the Moon, and therefore we do not see the Moon on planet Earth. As for the phenomenon of a solar eclipse, it occurs when the Moon is between the Earth and the Sun, which leads to us not seeing the Sun or part of it.
Scientists always advise us to avoid looking at the sun Directly, especially during a solar eclipse, so that we are not exposed to serious eye damage.
This requires the use of means to protect the eyes, such as goggles. All of this proves that the distance between the Earth and the sun is absolutely ideal, and if this distance is even slightly reduced, it will be disastrous for the inhabitants of the Earth.
In conclusion, the Earth’s rotation around itself and around the sun are scientific issues full of information, theories and profound knowledge, but they also require contemplation and contemplation of this wonderful geometry that points to the Creator Almighty.
