Fifth planet from Sun, Jupiter is the largest planet that dwells in our Solar System. The discovery of this giant planet was important because it proved that Earth was not the center of universe. First time after the discovery of Jupiter and 4 of its moons, it was seen that celestial objects were circling another body that was not Earth. Copernicus suggested that Earth was not the center of universe as it was believed back then. Over centuries, several other discoveries about this giant planet kept surprising the scientists all over the world. So, let us learn 40 interesting Jupiter facts and find out what’s there in that planet that keeps the astronomers busy!
Interesting Jupiter Facts: 1-5
1. Jupiter being the largest planet in our Solar System has been rightly named. Jupiter is the name of King of all gods in Roman Mythology.
2. The Greeks also named the planet after their god Zeus. Zeus was the king of all gods in Greek Mythology.
3. Jupiter was discovered in 1610 by Galileo Galilei. Galileo also discovered 4 of the moons of Jupiter. These moons are aptly called the Galilean moons in honor of their discoverer. The four moons discovered by Galileo were Callisto, Ganymede, Europa and Io.
4. Jupiter is so massive that its total mass is twice as much as the mass of all planets in Solar System combined together. Jupiter is capable of holding 1300 Earths in it. However, the mass of Jupiter is only 1 thousandths of the total mass of Sun.

5. Interestingly, if Jupiter had managed to grab 80 times more mass than its current mass, it would actually end up being a star instead of a planet.
6. Jupiter’s atmosphere is very similar to that of our Sun. The atmosphere is made up to mostly helium and hydrogen.
7. Jupiter is the fastest spinning planet in Solar System. It completes one rotation around its axis in just under 10 hours.
8. Jupiter is 7% wider at its equator compare to its width at the poles. This is because of its extreme spinning speed that makes the planet bulge out at its waistline.
9. The atmosphere of Jupiter is composed of 10.2% helium, 89.8% molecular hydrogen and trace amounts of ammonia hydrosulfide aerosols, water ice aerosols, water, ethane, hydrogen deuterite, ammonia and methane.
10. The core of Jupiter is massive and dense. Its composition is uncertain. The core is surrounded by a layer of helium-rich fluid metallic hydrogen and the whole thing is then wrapped up in an atmosphere that primarily consists of molecular hydrogen.
