Like all planets in our solar system, the Earth rotates in an elliptical orbit around the Sun. The difference between Earth's farthest point from the Sun and its closest point is very small. The also Earth revolves on an axis between the North and South poles. In relation to the Earth's orbit of the sun, this axis is tilted at 23.44 degrees. It is because of this tilt, known as the axial tilt, that we experience seasons and changes in the lengths of days as the Earth revolves around the sun. The time it takes for the Earth to make a single rotation is 24 hours (1 day). It takes around 365 days (1 year) for the Earth to orbit once around the Sun.
