how long does it take earth to orbit the sun

Earth takes approximately 365.256 days to complete one full orbit around the Sun. This period is also known as a sidereal year. During this time, Earth travels about 940 million kilometers (584 million miles) in its orbit, which is an ellipse with a very slight eccentricity, making it nearly circular. The average distance from the Earth to the Sun is about 149.6 million kilometers (93 million miles), which is also the basis of the astronomical unit (AU). In summary, Earth's orbit around the Sun takes just over 365 days, marking the length of an Earth year.
