The Earth does not move in a circle around the Sun but in an ellipse. So, the distance between the Earth and the Sun varies throughout the year. The closest point in the path of the Earth as it orbits the Sun is called perihelion. Every year, it happens in early January—at about January 3rd, to be exact—when the Earth is 147 million kilometers (about 91.4 million miles) away from the Sun.
