Which of the following solar terms is the slowest revolution speed of the earth?

The revolution of the earth is an elliptical orbit, so there is a difference between perihelion and perihelion. It's usually on July 6th. Because of precession, the perihelion of the earth is delayed by one day every 70.588 years. The perihelion of the earth in the last century was July 3, and now it is 65438+1October 4, two days before the summer solar term. In 14 1 year, the summer solar term will be the perihelion. When the earth is at perihelion, the angular velocity of revolution is the slowest.
