Question

How does the Sun have the gravity?

Answer 1

Hint: When two heavy bodies are together in space then it’s the gravitational force which holds them together. The bodies are either gaseous or solid. Any object which has mass contains its own gravity in space.

Complete answer:
In a solar system, planets revolve around the Sun the way the Moon revolves around the Earth. The reason behind this was given by Newton and then Kepler.
According to Newton, the planets orbit the Sun is related to why objects fall to Earth when we drop them. Gravitational force is a force which pulls the objects. That’s why, the Sun's gravity pulls on the planets same as the Earth's gravity pulls down anything that is not held up by some other force.
Heavier objects produce a bigger gravitational pull than the lighter ones thus the Sun exerts the strongest gravitational pull.
The gravitational field of any object is determined by two things: mass of the object and the distance. Thus, the Sun’s gravity can hold up to nine planets and also some dwarf planets.
The Sun’s gravitational pull is approximately 25 times more than the Earth. The sun's gravity pulls the planet toward the sun changing the direction of the orbit into a curve.
The gravitational force and the distance between the objects are inversely proportional to each other. Thus, the time to complete one orbit around the Sun for different planets is different. Hence the answer for the question has been obtained.

Note:
Any object containing a mass has its own gravity in space. The mass and the gravitational force are directly proportional to each other. If the distance between two objects weakens then the gravitational force between them weakens.
