Yes, it is true that the Earth goes around the Sun. This is called Earth's revolution, and it takes approximately 365.25 days to complete one full orbit.

Here's why it's true:

* Gravity: The Sun's massive gravity pulls on the Earth, keeping it in orbit.

* Centripetal force: The Earth's motion around the Sun creates a force called centripetal force, which balances the Sun's gravitational pull.

* Observations and evidence: We have observed the Earth's orbit through telescopes, spacecraft, and various astronomical observations.

It's important to note that the Earth's orbit isn't a perfect circle, but rather an ellipse. This means that the Earth is sometimes closer to the Sun and sometimes farther away.
