# How fast does the earth rotate around the Sun?

Average speed of Earth around Sun is 30 kilometer/second.

Pi times the orbit's diameter, 149.10 million kilograms, radius, and diameter divided by 149.10 million kilometers, plus 365.24 days and 365.24 x 24 x 60 x 60 seconds is the formula for circumference.
