As summer arrives, Taiwan experiences scorching heat with people often attributing it to the sun overhead. However, July 5th marks the day when Earth is farthest from the sun and the sun appears smallest. The distance at the 'aphelion' is approximately 5 million kilometers farther than the 'perihelion,' resulting in a decrease of about 7% in solar radiation received by Earth. Despite this, factors like Earth's tilt, Northern Hemisphere's direct sunlight, and landmass distribution contribute significantly to the summer heat, making it not merely due to the sun appearing 'big.' The Astronomy Museum explained the differences in solar diameter between the perihelion and aphelion, highlighting the elliptical orbit of Earth around the sun as a factor causing these variations.
