The planets revolve around the sun in orbits, and it is one of the important topics that scientists have been interested in throughout the ages and times to study and monitor and control the movement of the planets on these orbits in a permanent attempt to know the shape of these orbits and the mechanism and movement of the planets on them. Planets revolve around them in certain paths known as orbits.
Planets revolve around the sun in orbits
-
The planets revolve around the sun in fixed, elliptical, semi-circular orbits
Where the gravity of the sun affected the orbits of the planets, were it not for the presence of the sun, the planets would have moved in a straight line. -
Scientists have come to discover these orbits in the past due to their interest in studying them in a careful study, and perhaps the most famous of them is the scientist Kepler, who established all his thinking and research in the study of these orbits, a careful and careful study. This great scientist has reached three laws known as Kepler’s laws.
Why do planets revolve around the sun?
Scientists have been puzzled by this precise solar system, the unparalleled cosmic creativity, and how the planets revolve around the sun, which prompted them to investigate closely.
Until scientists eventually came to the conclusion that the real reason behind the planets revolving around the sun lies in the gravity of the sun, which works to make these planets revolve around them in fixed orbits, as the moon revolves around the earth because of the earth’s attraction to it.
Why do the planets remain in these orbits?
Scientists pointed out that the planets remain in these orbits due to two main reasons:
-
gravitational force:
This force is greatly affected by the mass of the two attracted bodies, which is directly proportional to the force of attraction, the greater the mass, the greater the force of attraction between the two bodies. -
inertia:
The movement of the planets takes a straight shape in space while the sun is pulling the planets towards it by gravity, which eventually changes their direction and turns its path into a curved orbit around the sun.
Why do the planets revolve around the sun from west to east?
-
Scientists pointed out that there is no clear scientific reason for the movement of the planets around the sun from west to east, but some have strived to find out the real reason behind this mechanism and concluded that the tilt of the planetary axis due to collisions that occurred during the formation and formation of the solar system is the closest reason to explain this mechanism, that is, it arose During the formation of the solar system regarding 5 billion years ago.
-
Since this solar system originated from the Big Bang, scientists have noticed that all the planets revolve around the sun from west to east except for Venus and Uranus, which rotate from east to west.
-
Scientists have suggested that as a result of their exposure to frequent strong collisions from space objects that caused the reversal of their rotation, and some suggested that the tides and ebb and flow of the strong gravity of the sun to Venus in particular might be the reason for this.
The speed of the planets revolving around the sun
This speed varies according to a number of factors, the most important of which is the proximity or distance from the sun. The speed of the planets increases as they get closer to the sun, so we will explain this in detail through the following table:
| planet | The speed of the planets revolving around the sun |
|
Mercury |
47.87 km/s, or regarding 88 days. |
|
Flower |
35.02 km/s, which is regarding 225 days. |
|
Earth |
29.78 km/s or regarding 365 days. |
|
Mars |
24,007 km/s, which is regarding 687 days. |
|
Buyer |
13.07 km/s, which is regarding 12 years. |
|
Saturn |
9.69 km/s, which is regarding 29 years. |
|
Uranus |
6.81 km/s, which is regarding 84 years. |
|
Neptune |
5.43 km/s, which is regarding 164 years. |
|
Pluto |
4.74 km/s, which is regarding 248 years. |

Paths of the planets around the sun
Planets, moons and stars revolve around the sun in paths, so we will provide some basic information regarding the movement of the planets of this solar system:
-
Planet Mercury:
The smallest planet and the closest to the sun, which is regarding 58 million km away from it, does not go through seasons due to its rotation in a straight position due to the inclination of its axis by two degrees. -
Venus:
The second closest planet to the sun, with an estimated distance of regarding 108 million km, is the hottest planet ever. -
planet earth:
Known as the planet of life, it is the third planet, as it is regarding 150 million km away from the sun, and it has four seasons, due to the tilt of its axis by 23.4 degrees. -
Mars
Known as the red planet and is currently subject to accurate scientific studies, it is the fourth planet and is regarding 228 million km away from the sun. -
Jupiter:
It is the largest planet in the solar system and is regarding 778 million km away from the sun. It has no changing seasons due to its vertical rotation due to the inclination of its axis by 3 degrees. -
Saturn:
The second largest of the planets following Jupiter, it is characterized by the presence of an icy circular ring that gives it a distinctive shape. It is regarding 1.4 billion km away from the Sun. It passes through distinct seasons due to the tilt of its axis by 26.7 degrees. -
Planet Uranus:
It is one of the oldest planets that have been discovered. It is regarding 2.9 billion km away from the Sun. It is considered one of the planets with the most extreme seasons due to the tilt of its axis of 97.77 degrees. -
Neptune:
It sparkles in space with a beautiful blue color due to the presence of hydrogen and helium gas in its atmosphere. It is difficult to see with the naked eye due to its distance from the sun, where the distance between it and the sun is estimated at regarding 4.5 billion km. -
Pluto:
Known as the dwarf planet due to its small size, it is the last planet in the solar system and the farthest from the sun, with an estimated distance of regarding 5.9 billion km.
Thus, it has been recognized that the planets revolve around the sun in orbits as one of the important matters that scientists have been interested in studying since ancient times until they came to the idea of the heliocentricity of the universe and the planets orbiting around it in orbits.
