The answer lies in the , not our distance from the Sun. The Earth is tilted at an angle of roughly 23.5 degrees .
The timing of perihelion shifts very slowly over thousands of years due to axial precession. Approximately 13,000 years from now, perihelion will align with July, reversing the seasonal distance relationship. However, for the present epoch, the closest approach remains firmly in January. during which month is the earth closest to the sun
The Earth is closest to the Sun during the month of . The answer lies in the , not our distance from the Sun
Earth reaches perihelion in early January , typically between January 2 and January 5. In recent decades, the date has varied slightly due to gravitational perturbations from Jupiter and other planets. For example, in 2024, perihelion occurred on January 3. Therefore, the month during which Earth is closest to the Sun is January . Approximately 13,000 years from now, perihelion will align
One of the most interesting side effects of being closest to the Sun in January is the speed at which our planet travels. According to Kepler’s Second Law of Planetary Motion, a planet moves faster when it is closer to its star.
The "stretch" of this ellipse is known as . Earth’s eccentricity is currently very low (about 0.0167), meaning our orbit is almost circular, but that small 3-million-mile difference is still enough to define our perihelion every January. If We Are Closer, Why Is It Cold?
