A video shows the objects in the solar system orbiting the Sun. Why do objects orbit the sun?
A. The sun is so bright that objects are forced away.
B. The sun is so massive that it has most gravity.
C. The sun is releasing heat and pushing objects away.
D. The sun is moving so quickly that other objects move around it.
B. The sun is so massive that it has most gravity.
hello
B. The sun is so massive that it has most gravity.
The correct answer is B. The sun is so massive that it has the most gravity.
To understand why objects orbit the sun, we need to know about gravity. Gravity is the force of attraction between two objects with mass. The strength of gravity depends on the mass of the objects and the distance between them.
In the case of the solar system, the sun is the most massive object and has a tremendous amount of gravitational pull. Planets, asteroids, and other objects in the solar system, including artificial satellites, are all affected by this gravitational force.
When an object is in space and close enough to a larger object, such as the sun, it experiences a gravitational force towards that object. This force, which always pulls objects inward, is what keeps planets and other objects in orbit around the sun.
Imagine throwing a ball on level ground. If you throw it with enough speed, it will follow a curved path and eventually fall back to the ground due to the force of gravity. This is similar to how objects in the solar system orbit the sun. Their forward motion and the gravitational pull of the sun combine to create a curved path, continuously pulling them towards the sun but also causing them to move forward.
So, the reason objects orbit the sun is because the sun's massive gravity keeps them locked in a continuous balance between falling towards it and moving forward. The sun's gravity is much stronger than any other object in the solar system, which is why all other objects orbit around it.
