During Which Month Is The Earth Closest To The Sun Link Better

To visually understand how Earth's elliptical path places it closest to the sun in January and farthest in July, consider the orbital diagram below. Note that the eccentricity of the ellipse is visually exaggerated here to clearly show the difference between the two points: Exact Dates of Perihelion and Aphelion

January: When Earth Makes Its Closest Approach to the Sun Contrary to what the freezing temperatures in the Northern Hemisphere might suggest, Earth is actually closest to the Sun during the month of . This annual astronomical event is known as perihelion . Understanding Perihelion during which month is the earth closest to the sun link

The 3% increase in solar intensity during perihelion does have a subtle effect, however. It makes winters in the Northern Hemisphere slightly milder than they would be if the orbit were perfectly circular, and it intensifies the summer heat in the Southern Hemisphere. The Changing Dates of Perihelion To visually understand how Earth's elliptical path places

The reason our distance from the Sun fluctuates throughout the year lies in the geometry of our orbit. Understanding Perihelion The 3% increase in solar intensity

This annual astronomical event is called . During this time, Earth is approximately 147 million kilometres (91.4 million miles) from the sun, which is about 5 million kilometres (3 million miles) closer than it is at its farthest point in July. Why Perihelion Occurs

A notable feature of perihelion is that despite being closest to the sun, the Northern Hemisphere experiences winter. This is because the tilt of Earth's axis (not the distance from the sun) primarily governs the seasons — the Northern Hemisphere is tilted away from the sun at that time, so sunlight arrives at a lower angle and spreads over a larger area, resulting in cooler temperatures.

The timing of perihelion is not static over very long periods. Due to a slow, continuous change in the orientation of Earth's elliptical orbit—a phenomenon known as apsidal precession —the date of perihelion shifts gradually over a cycle of about 21,000 years. Approximately 10,000 years from now, the perihelion will occur in July, meaning the Northern Hemisphere's summers will be hotter and its winters colder, due to the combined effect of axial tilt and proximity to the Sun.
