This January 4, Earth will reach perihelion, greater proximity to the Sun in its annual orbit. If on average, the Earth moves in its orbit at an average speed of 107,280 kilometers per hour, tomorrow it will reach its maximum speed, reaching 110,700 kilometers per hour.
On the other hand, in its turn around the Sun, describing an elliptical orbit of 93 million kilometers, the Earth moves at a slower speed when it reaches the aphelion, the distance furthest from the Sun, traveling at 103,536 kilometers per hour, more than 7,000 kilometers per hour apart.
The perihelion will occur at 10.59 UTC on January 4. The aphelion in 2017 will be July 3. The average distance from the Sun is on average 150 million kilometers. In the aphelion it reaches 152.09 million kilometers and in the perihelion it falls to 147.10 million kilometers away.
But this is nothing: we must remember that, in turn, everything moves at great speeds. For example, the Sun is not still. It is launched at 790,000 kilometers per hour towards the center of the Milky Way. So, the Sun (and all the planets around it, the Solar System) take a full turn in the milky way of the Milky Way in 200 million years.
