The True Size of the Sun

They say you can fit 1.3 million Earths inside the Sun. <break time="1.0s" /> But… that number’s

not quite right. <break time="1.0s" /> That 1.3 million figure comes from dividing the Sun’s volume — about 1.41

× 10²⁷ cubic meters — by Earth’s volume, which is 1.08 × 10²¹ cubic meters. <break time="1.0s" />

It’s like saying you could pour planets into the Sun as if they were fluid droplets. <break time="1.0s" />

But in reality, planets are spheres, and spheres can’t pack perfectly.<break time="1.0s" /> Even in the most

efficient arrangement — called hexagonal close packing — only about 74% of space is filled. <break time="1.0s" />

So, when you factor that in, the true number isn’t 1.3 million

Earths… it’s closer to 960,000. <break time="1.0s" /> Still, that’s nearly a million entire Earths
