You could fit nearly one million Earth-sized planets and also the sun isn't also that big of a star.

You are watching: How many jupiters fit into the sun

From the vantage point of a human, our civilization truly is huge. However, in the grand, cosmic plan of things, the planet is however a fall in the solar bucket.


The sun is a star in ~ the center of the solar system, a sphere made up of hot plasma and magnetic fields. That diameter is about 1,392,000 kilometres (864,000 miles), almost 109 times larger than the Earth, and also its massive is 330,000 times the of the Earth. In fact, through mass, the sun makes up over 99.86% the the solar system, whereas gas giants like Jupiter and also Saturn make up most the the continuing to be 0.14%.

In bespeak to understand the sheer scale of the sun, it’s worth asking the question: how many Earth-sized planets have the right to you fit inside the sun?

Volume-wise, you might fit almost 1.3 million Earths right into the sunlight (1.412 x 1018km3). That’s assuming all those countless Earths room squished in addition to no empty space in between. Yet the Earth’s form is spherical not a cube, for this reason only around 960,000 Earths would fit inside the volume that the sun.

Here’s how it would look choose (approximately) if the planet was a small blue marble:

The sunlight is just an average-sized star, though. Because that instance, the red giant Betelgeuse has actually a radius 936 times that of the sun, making that billions the times larger in volume than the Earth.

And that’s nothing. VY Canis Majoris is thought to have between 1,800 and also 2,100 times the radius that the sun. Therefore, you might fit dozens of billions the Earths in several of the largest stars in the universe.

Earth is no the largest nor the smallest world in the solar system. Mercury (0.055 time Earth’s volume), Venus (0.85 time Eath’s volume), and also Mars (0.151 times Earth’s volume) room all smaller than Earth. It would certainly take 17.45 million Mercury-sized planets, 1.12 million Venus-sized planets, and also 6.3 million Mars-sized planets to to fill the sun, gaps not included.

On opposing end, you can fit 726 Jupiter-sized planets (1,321 times the volume that Earth) and also 1,256 Saturn-sized planets (764 times the volume that Earth) inside a hollow sun, gaps not included.

In the future, you might cram even more Earths or Jupiters right into the sun. Together it drags closer to the end of the lifecycle, the sunlight gets both hotter and also larger together it proceeds to fuse hydrogen into helium at its core. As soon as it runs out of fuel, the core will collapse and heat up ferociously, leading to the sun’s external layers come expand.

By astronomers’ calculations, the sun is already 20% larger than at the time of the formation about five billion year ago. In an additional five exchange rate years, when it will reach that helium-burning phase, the sun will turn right into a red giant. It will certainly be so huge at this time that it will completely engulf the planets Mercury, Venus, and perhaps also Earth.
