To understand why Earth has a closest point, you must first understand that Earth’s orbit is not a perfect circle.
Earth doesn’t sit upright; it tilts at an angle of about 23.5 degrees.
While Earth’s orbit is nearly circular, it is slightly "eccentric." This slight stretch in our orbital path means there is about a 3-million-mile difference between our closest and farthest points. If We Are Closer in January, Why Is It Cold? when is earth closest to the sun
If you need a quick, memorable answer:
Perihelion has several implications for our planet: To understand why Earth has a closest point,
in the sky at perihelion than at aphelion, though this difference is too subtle to detect with the naked eye. Why does Earth get colder when we are closest to the Sun 29 Dec 2025 —
Here’s a solid, SEO-friendly blog post that tackles a common misconception about Earth’s orbit. If We Are Closer in January, Why Is It Cold
The exact date and time shift slightly from year to year due to variations in Earth's orbit. These minor shifts are caused by the gravitational pull of other celestial bodies, primarily the Moon and larger planets like Jupiter and Saturn. Why Our Orbit Isn't a Perfect Circle
While the distance change is subtle, it does have some minor physical effects:
As we go about our daily lives, it's easy to take for granted the intricate dance of celestial bodies that govern our planet's climate, seasons, and overall existence. One crucial aspect of this dance is Earth's orbit around the Sun, which is not a perfect circle, but rather an ellipse. This elliptical shape means that our distance from the Sun varies throughout the year, with the closest point being a significant event in the astronomical calendar. So, when is Earth closest to the Sun?
