This is the crucial piece of the puzzle. Seasons are not caused by our distance from the sun. They are caused by (about 23.5 degrees).
So, the next time someone wonders why it's cold in January despite our planet being millions of miles closer to the sun, you'll have the answer. Earth's 23.5-degree axial tilt is the dominant force shaping our seasons. The tilt's influence on the angle and duration of sunlight completely overshadows the small energy boost we get from our slight orbital proximity. The next time you look up at a low, pale winter sun, remember that while Earth is at its closest, the sky itself is telling a different, more important story about what truly drives our seasons.
: At this point, Earth is roughly 147.1 million kilometers (91.4 million miles) from the Sun. when is earth closest to the sun
The most common myth is that our distance from the sun causes the seasons. If that were true, the entire world would be roasting in January and freezing in July. In reality, axial tilt
In fact, perihelion occurs during winter in the Northern Hemisphere, around January 4th, while the Southern Hemisphere experiences summer. This apparent paradox is due to the fact that Earth's axial tilt and orbital plane are not aligned. As a result, the distribution of solar energy throughout the year is not directly correlated with the distance from the Sun. This is the crucial piece of the puzzle
In the 17th century, astronomer Johannes Kepler discovered that planets do not travel in perfect circles. Instead, they travel in , which are elongated or oval-shaped paths.
To understand why this happens, we have to look at the shape of Earth's orbit. So, the next time someone wonders why it's
Because of the inverse-square law (intensity of light decreases with the square of the distance), Earth receives about at perihelion (January) than at aphelion (July).
Seasons are caused entirely by the , not its distance from the Sun.
: The point where Earth is farthest from the Sun. The prefix apo means "away from." When Does Perihelion Occur?
