I Measured the Sun’s Size to Test NASA’s Orbit Claim – Here’s What I Found

NASA says Earth moves in an elliptical orbit around the Sun, from about 91.4 million miles in January (perihelion) to 94.5 million miles in July (aphelion). That change should cause the Sun to appear slightly smaller in the sky — about 3.39% smaller, to be exact.

So I tested it.

I photographed the Sun at solar noon on January 3rd and again on June 27th using the exact same camera, zoom, and settings. The only difference? Earth’s position in orbit.

Here’s what I measured:

January 3rd: 2,520 pixels tall

June 27th: 2,429 pixels tall

Pixel size change: 3.61%

That’s nearly a perfect match to NASA’s predicted 3.39%. No space agency required — just a solar filter, a Nikon P950, and two afternoons.

I had to take the June shot early because I’ll be traveling during aphelion (July 3rd), but this is close enough to prove the point.

This video debunks the flat Earth claim that “the Sun never changes size” — and it does it with basic photography and math.
