When Earth Is Closest To The Sun -

Earth is tilted at an angle of 23.5 degrees. During January, the Northern Hemisphere is tilted away from the sun. This means solar rays hit the north at a shallow angle, spreading the energy over a larger area and providing less concentrated heat. Additionally, the days are shorter, providing less time for the atmosphere to warm up.

While the change in distance isn't the primary driver of the seasons, it does have measurable effects on our planet’s movement and climate: Orbital Speed when earth is closest to the sun

A countdown clock synced to Earth’s orbital speed, ticking slower as perihelion peaks. Earth is tilted at an angle of 23

The word perihelion comes from the Greek words "peri," meaning near, and "helios," meaning sun. It describes the specific point in Earth's annual orbit where it reaches its minimum distance from our star. Additionally, the days are shorter, providing less time

Perihelion occurs annually in early January, typically falling between the 1st and the 4th of the month.
