"The reason perihelion happens in January isn't random," Elias explained. "It shifts over thousands of years. Right now, and for the last few centuries, the timing of Earth’s closest approach is dictated by the gravitational pull of Jupiter. Our giant neighbor tugs on our orbit, influencing exactly when we swing close to the Sun."

So, the specific month in which the Earth is closest to the sun is not fixed for eternity. However, for your lifetime and the next several thousand years, the answer will remain . "The reason perihelion happens in January isn't random,"
Each year Earth follows an elliptical orbit around the Sun. Because that orbit isn’t a perfect circle, there’s a point when Earth is closest to the Sun (perihelion) and a point when it’s farthest (aphelion). Perihelion typically occurs in early January—usually around January 2–5—while aphelion occurs in early July. That means Earth is nearest the Sun in January, not during the northern-hemisphere summer.
