The number of planets in the solar system certainly makes many people wonder, whether the cause of the many planets does not collide with each other.
—
Then, what are the factors that cause the planets do not collide with each other? Quoting a book Solar System Physics the work of Prof. Dr. Suryadi Siregar, DEA, here is the explanation.

What Factors Keep the Planets From Colliding?

Every planet in the solar system has its own orbit. This orbit is one of the factors why the planets do not collide with each other.
—
Launch the journal about Satellite Orbit and Altitude by Husni Nasution, orbit is the path traversed by celestial objects in their orbit around objects sky another with a greater gravitational force. —This indicates that not only planets actually have orbits, other celestial bodies in the solar system also have orbits.
—
The orbit itself is usually circular or elliptical, each planet has its own speed when around it. Earth, for example, has a speed of 48 kilometers per second. While Mars only has a speed of 38 kilometers per second.
—
The orbit also keeps the planets from going out of their trajectory, that’s why it’s rare for planets to collide with each other.
—
In addition to orbits, each planet also has its own mass. Therefore, the planets in the solar system have a gravitational force. The greater the mass, the greater the gravitational force it has.
—
In the solar system itself, the sun is the celestial body that has the most mass. Therefore, style gravity possessed by the sun is able to make the planets around it revolve around it.—It is also still related to the orbit. The reason is, each planet that the sun pulls to orbit it will pass through a predetermined orbit.
—
The gravitational force on the sun also makes all the planets have their respective distances. Therefore, the orbits of each planet remain far apart and do not collide with each other.
