The misconception that Earth is closest to the sun in January is a common one. In reality, Earth is actually closest to the sun during the northern hemisphere's summer, around early January. This phenomenon is known as perihelion.
The Earth's orbit around the sun is not a perfect circle but an ellipse, meaning that its distance from the sun varies throughout the year. The point of the orbit where Earth is closest to the sun is called perihelion, while the point furthest from the sun is called aphelion.
The tilt of Earth's axis is the primary factor behind the seasons. During the northern hemisphere's winter (January), it is tilted away from the sun. Contrary to common intuition, the distance between Earth and the sun has a minimal effect on the seasons. Seasonal changes primarily occur due to the tilt of Earth's axis, which causes the distribution of sunlight to change, resulting in variations in temperature.
Therefore, the Earth's distance from the sun during the northern hemisphere's winter has little to do with the actual seasons we experience.
