Perihelion

Perihelion is the point in Earth's orbit when it is closest to the Sun. As Earth travels around the Sun in an elliptical (oval-shaped) orbit, its distance varies. When Earth reaches perihelion, typically around January 3rd, it is about 147 million kilometers (91 million miles) from the Sun. This position affects seasonal intensity and climate slightly, though other factors like axial tilt play a larger role in seasons. Perihelion is a natural part of Earth's orbital cycle, which influences the planet's climate, solar energy receipt, and orbital dynamics.
