Summary:

• **How Gravity Keeps Earth in Orbit**: Gravity is an invisible force that pulls objects toward each other. The Sun's gravity is so strong that it pulls Earth toward it, but Earth is also moving sideways really fast, which keeps it from falling into the Sun. This perfect balance is what keeps Earth traveling around the Sun in a circle, kind of like a ball on a string spinning around.

• **Earth's Journey Through Space**: Earth doesn't just orbit the Sun—it's also moving through space in many different ways at the same time. Our planet travels around the Sun, spins like a top, and moves with our entire galaxy through the universe. All of these movements together create Earth's amazing journey through the cosmos.
