 How fast does the Earth orbit around the sun?

The Earth travels around the sun at a velocity of about 18.6 miles (29.8 kilometers) per second. This number is based on the distance divided by the time it takes to get around the sun: The circumference of the Earth's orbit is 584,116,000 miles (940 million kilometers) and the travel time is 365.25 days (or 8,766 hours), so 584,116,000 miles divided by 8,766 hours equals 66,634 miles (107,2]5 kilometers) per hour, or 18.6 miles (30 kilometers) per second. In other words, every second you read this book,the Earth's orbit is carrying you 18.6 miles (30 kilometers) through space.
