r = a (1 - e^2) / (1 + e cos(θ))
Perihelion occurs when the Earth is at its closest point to the Sun, approximately 91.5 million miles (147 million kilometers) away. This event typically takes place around early January, with the exact date varying slightly from year to year due to the Earth's elliptical orbit and the gravitational influences of other planets. when is earth closest to the sun
This variation in solar energy has several effects: r = a (1 - e^2) / (1
: While the Sun's intensity is about 7% greater at perihelion than at aphelion, the effect on global climate is minimal because the Southern Hemisphere (which is tilted toward the Sun in January) is mostly water, which absorbs heat more steadily than land.
