When we talk about the sun being "bigger" than Earth, we're actually talking about two different measurements that tell wildly different stories. The sun's mass is about 330,000 times that of Earth. But if we're talking about volume—how much space it takes up—the sun is roughly 1.3 million times larger. You could fit over a million Earths inside the sun and still have room to spare.

To put that in perspective, imagine Earth as a marble. The sun would be a beach ball about 5 feet across sitting next to it.

The Solar System's Gravitational Bully

The sun's enormous mass gives it an almost absurd level of control over our cosmic neighborhood. It makes up 99.86% of the entire solar system's mass. Jupiter, Saturn, and all the other planets, moons, asteroids, and comets combined? They're fighting over the remaining 0.14%.

This is why the sun's gravity dominates everything within hundreds of billions of miles. Earth isn't orbiting around some central point in space—it's orbiting around the sun because the sun's mass is so overwhelming that it essentially is the center of mass for the entire system.

Size Comparisons That Break Your Brain

The sun's diameter is 109 times Earth's diameter—you could line up 109 Earths across the sun's face
The sun's surface area is roughly 12,000 times Earth's surface area
The sun's radius extends about 432,000 miles, compared to Earth's 3,959 miles

What makes these numbers even more staggering is that the sun is actually a pretty average star. It's classified as a G-type main-sequence star—basically, the cosmic equivalent of "medium." There are stars out there like UY Scuti that would extend past Jupiter's orbit if placed where our sun is.

Despite being 93 million miles away, the sun's radiation reaches Earth in just 8 minutes and 20 seconds, delivering enough energy to power all of Earth's weather systems, ocean currents, and nearly all life on the planet. Every second, the sun converts about 600 million tons of hydrogen into helium through nuclear fusion, releasing energy equivalent to billions of nuclear bombs. And it's been doing this for 4.6 billion years.
