The Sun's Disk Will Reach Its Smallest Size Today

The sun's apparent disk will reach its smallest size today as Earth reaches its farthest point from the sun in its orbital path around the star.

• Earth is currently at its farthest distance from the sun, a point known as aphelion
• The sun will appear smallest in the sky from Earth's perspective today
• This occurs annually when Earth is at aphelion in its elliptical orbit. Despite the sun appearing smaller today, the Northern Hemisphere is currently experiencing summer, while the Southern Hemisphere is in winter, demonstrating that Earth's distance from the sun is not the primary factor determining seasons — rather, the tilt of Earth's axis relative to the sun determines seasonal changes.
