The Earth takes approximately 365.25 days, or one year, to complete a full orbit around the Sun. This period is often referred to as a sidereal year and is about 365.26 days in length
. Earth's orbit around the Sun is elliptical, not perfectly circular, which means the exact time to complete one revolution can vary slightly depending on its position in the orbit, such as being closer to the Sun at perihelion or farther at aphelion
. During this orbit, Earth travels at an average speed of about 29.78 kilometers per second (approximately 107,000 kilometers per hour or 66,700 miles per hour)
. The total distance Earth covers in one orbit is roughly 940 million kilometers (about 584 million miles)
. In summary, it takes Earth just over one year-about 365.25 days-to orbit the Sun once, moving at nearly 30 km/s along an elliptical path
