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

From the vantage allude of a human, our human being truly is huge. However, in the grand, cosmic system of things, the planet is however a autumn in the solar bucket.

The sun is a star at the facility of the solar system, a sphere made up of hot plasma and also magnetic fields. That diameter is about 1,392,000 kilometres (864,000 miles), nearly 109 times bigger than the Earth, and also its massive is 330,000 times the of the Earth. In fact, by mass, the sun renders up over 99.86% that the solar system, conversely, gas giants like Jupiter and Saturn consist of most of the staying 0.14%.

In stimulate to recognize the sheer range of the sun, it’s worth questioning the question: how numerous Earth-sized planets deserve to you fit inside the sun?


Volume-wise, you might fit virtually 1.3 million Earths into the sunlight (1.412 x 1018km3). That’s assuming every those numerous Earths room squished in addition to no empty space in between. Yet the Earth’s form is spherical no a cube, so only about 960,000 Earths would fit within the volume that the sun.

Here’s exactly how it would look like (approximately) if the earth was a small blue marble:

The sunlight is just an average-sized star, though. For instance, the red huge Betelgeuse has a radius 936 times that of the sun, making it billions the times larger in volume 보다 the Earth.

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

Earth is no the largest nor the smallest earth in the solar system. Mercury (0.055 times Earth’s volume), Venus (0.85 time Eath’s volume), and also Mars (0.151 time Earth’s volume) room all smaller sized than Earth. It would take 17.45 million Mercury-sized planets, 1.12 million Venus-sized planets, and 6.3 million Mars-sized planets to fill the sun, gaps no included.

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


In the future, you could cram even an ext Earths or Jupiters right into the sun. As it drags closer come the finish of the lifecycle, the sun gets both hotter and larger as it proceeds to fuse hydrogen into helium at its core. As soon as it runs the end of fuel, the core will collapse and heat increase ferociously, leading to the sun’s outer layers to expand.

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