Humans like to measure objects by seeing how many objects can fit into another, single object. We often ask how many moons can fit in the Earth, or how many Earths can fit in the sun. Doing this helps us understand the size of objects. You may wonder how many Earths can fit in other planets, like Jupiter. To see how many Earths can fit in Jupiter, let’s take a look at the measurements and size of Jupiter itself. After understanding Jupiter’s size, we can thoroughly see why 1,300 Earths would fit inside Jupiter.
Jupiter happens to be the largest planet in our Solar System, and it is classified as a “gas giant.” This classification is appropriate because Jupiter is so massive that it could become a star if it took on about 80 times more mass than it has now. Scientists even say that Jupiter and its moons are similar to our Solar System in how they work.
Naturally, Jupiter has the strongest magnetic field of all the planets, with a field that is 20,000 times that of Earth’s magnetic field. The gravity is much different too. Having more gravitational pull, someone standing on Jupiter would measure 2.4 times their Earth weight on Jupiter. That means if you weigh 120 pounds on Earth, then you would weigh 288 pounds on Jupiter.
Earth is much smaller than Jupiter. Earth is about 3,959 miles, while Jupiter measures in at 43,441 miles. Earth is 5.972 × 10^24 kg, while Jupiter is 1.898 × 10^27 kg. While Earth only has one moon, Jupiter has 16 confirmed moons. Jupiter also has four rings.
With such a size different, it only makes sense that 1,300 Earths could fit inside of Jupiter. It would take 3.5 Earths alone just to fit across Jupiter’s red spot. Jupiter is massive compared to our tiny planet, so it would naturally take this many Earths to fill Jupiter.
