Here's a breakdown:

* Gravity: Every object in the universe with mass attracts every other object with mass. This force of attraction is called gravity. The more massive an object, the stronger its gravitational pull.

* Earth and Sun: The Sun is much more massive than the Earth. This means the Sun's gravitational pull is much stronger than the Earth's.

* Orbiting: This strong gravitational pull from the Sun keeps the Earth in its orbit around the Sun. It's like a giant invisible string holding the Earth in place.

Important points:

* Mutual Attraction: While the Sun exerts a stronger gravitational pull on Earth, it's important to remember that the Earth also exerts a gravitational pull on the Sun. It's just that the Sun is so much more massive that its pull is much stronger.

* Balance: The gravitational pull between the Sun and Earth is balanced, which is why the Earth stays in its orbit and doesn't crash into the Sun.

In simpler terms: The Earth is like a little ball being held by the Sun's strong gravitational pull. The Sun is so big and strong that it keeps the Earth from flying off into space, making it go round and round in a circle.
