Being massive, Jupiter stands as the largest planet in the solar system. It is also the fifth planet from the sun. The planet Jupiter is classified as a Gas Giant together with other similar planets including Neptune, Uranus, and Saturn. These four planets are combined to call Jovian planets. The planet was discovered in the prehistoric times but the discoverer is yet to be known. Jupiter is predominantly composed of hydrogen with some portion of helium. It does not have a real solid surface. Robotic spacecraft has explored the Jupiter on number of occasions. It is believed to be the fastest spinning planet in our solar system in that the planet only takes 10 hours to complete a full rotation on its axis. Be ready for the most amazing Jupiter facts for kids including Jupiter’s mass, atmosphere, temperature, moons, gravity, and characteristics.
Jupiter Facts For Kids
The gigantic Jupiter is believed to give out more energy than it receives from the sun. You might be wondering as to where the extra energy comes from! Actually, Jupiter is capable of generating its own heat that produces from within the planet as a result of gravitational force, which is why you can classify Jupiter as a star. According to scientists, the earthlings should be thankful to Jupiter for its strong gravity seizes several incoming asteroids and comets that would otherwise have crashed into earth. We can say that there would possibly be no life on earth without the planet Jupiter.

- One of the most fascinating features of Jupiter is its Great Red Spot which seem to exist for almost 350 years. This spot is deemed to be shrinking.
- Jupiter has planetary rings which are fairly dimmer as compared to that of Saturn’s.
- The planet has the strongest magnetic field among all planets which is why compasses believe to work on Jupiter.
- Jupiter has total 63 moons; all of them are less than 10 km in diameter.
- The spacecraft (from earth) has visited Jupiter 7 times.
- After Venus and Moon, Jupiter is by far the brightest planet in the solar system.
- The Jupiter can hold more than 1,300 earths in it.
- The Voyager I observed at least eight active volcanoes on I0 and plumes spreading up to 250 km above the surface.
