The word perihelion originates from the Greek words peri (meaning near) and helios (meaning sun). This proximity occurs because the Earth’s orbit around the Sun is not a flawless circle but rather an (a slightly squashed, oval shape).
The Earth sits on a slant, leaning at an angle of roughly 23.5 degrees. During the northern winter, the Northern Hemisphere is tilted away from the sun. This tilt causes the sun’s rays to strike the northern half of the globe at a glancing angle, spreading the light over a larger surface area and reducing the intensity of the heat. The days are shorter, the nights are longer, and the sun hangs low in the sky. what season are we closest to the sun
The simple, direct answer is:
As Earth orbits the sun, this tilt remains fixed in space, causing different hemispheres to "lean" toward or away from the sun at different points in the year. In January: What Causes the Seasons? | NASA Space Place The word perihelion originates from the Greek words
This means the Earth is roughly to the Sun in January than it is in July. Why Distance Does Not Cause the Seasons During the northern winter, the Northern Hemisphere is
