Jakarta, Borneo24.com – In our solar system there are many celestial bodies from the Sun as the center, planets, and asteroids. All the planets revolve around the Sun continuously for billions of years. But do you know why the planets don’t collide with each other? Let’s look at the material below to find out the answer.
The moving planets do not collide with each other because they have their own orbits that are governed by the force of gravity. All objects that have mass will have a gravitational force. The greater the mass, the greater the gravitational force it causes. The sun is the center of the solar system because it has the most mass, because 99% of our solar system is the sun.
Since their appearance, the planets have been moving at a constant speed. Reporting from NASA Space Place, then the Sun’s gravitational force pulls the planets closer to it, forcing them to move in an orbit around the Sun.
However, the Sun’s gravitational force still depends on the distance, so the orbits of each planet remain far apart and do not interfere with each other.
Planetary orbits are not always spherical, but some are oval or elliptical. The faster the natural movement of a planet, the more elliptical its orbit is. Then the question is if the planets are attracted by the Sun’s gravitational force, why aren’t the planets attracted to the Sun? The answer is that the Sun’s gravity is not strong enough to pull the planet to its core and so is the inertial force due to the planet’s natural velocity.
Reporting from Sciencing, the inertial force makes the planets tend to want to move in a straight line instead of turning, creating an outward force as shown in the picture. The outward force created by inertia will always oppose the Sun’s gravity, but still cannot escape the Sun’s influence. This is why the planets can stay in their respective orbits without colliding with each other.
Planets also have different distances so that the influence of the Sun’s gravitational force is also different. So that the orbits of different planets do not overlap and collide. Simply put, the planet’s motion is like a dog tied to a rope, then the end of the rope is tied to a pole. Dogs will always run in a straight line, but are attracted by the ropes so that they unconsciously run in circles that are like planetary orbits. (***)
