Do you think that one day we can go to Jupiter? Yes! Someday we can go but we need to think about how we could stand on it. So here are five huge Jupiter facts for kids.

Jupiter Facts for Kids Fact Number 1: Jupiter is The Largest Planet in Our Solar System

If you were to combine all the planets in the solar system together and double that size, you would
get close to the size of Jupiter. The diameter of Jupiter is over 140,000 km long, which is about
15,000 times as tall as Mount Everest. It is 11 times as wide as Earth. It is estimated that roughly
1,300 Earth’s could fit inside Jupiter.

Jupiter Facts for Kids Fact Number 2: Jupiter is The Fastest Spinning Planet in The Solar System

Not only is Jupiter the largest planet but it is also the fastest. It only takes about 10 hours for Jupiter
to complete a full rotation on its axis, meaning that a full day on Jupiter is only 10 hours long. Jupiter
has the shortest day in the solar system. Although a day is very short on Jupiter, a year is quite long.
One year on Jupiter is the same as nearly 12 Earth years.

The big storm on Jupiter is known as the Great Red Spot. The Red Spot is an anticyclone because the
storm rotates counterclockwise in the Southern Hemisphere. It has been studied for over 150 years
and it is estimated that the Great Red Spot has been on Jupiter for over 300 years. The Red Spot is
slowly shrinking, today the Great Red Spot could fit planet Earth inside it, however a few centuries
ago roughly three planet Earths could fit inside it.

With 80 moons, Jupiter has the second most moons in the solar system. Fifty-seven moons have
been given official names by the International Astronomical Union (IAU). Another 23 moons are
awaiting official names. Galileo Galilei first observed Jupiter’s four largest moons in 1610. These four
moons were given the names Io, Europa, Ganymede, and Callisto. These are the largest moons in the
Solar System, with Ganymede taking the title of the largest moon. It is bigger than the planet

Jupiter is a gaseous planet meaning it is made up of liquid and gases, predominantly hydrogen and
helium. If you tried to stand on Jupiter you would have nothing to stand on and instead would sink
down and be crushed by the intense pressure inside Jupiter. It is impossible for anything to land on
the planet Jupiter.
