What is earth’s approximate rate of movement along its orbit?

Well done! You have accurately described the revolution of Earth around the sun. Over the course of 365 days, 6 hours, and 9 minutes, our planet completes one full orbit while maintaining a constant speed ranging from 29.29 to 30.29 km/s. It's important to note that this duration is measured with reference to the stars, also known as a sidereal year. Thanks for sharing this scientific insight!
