Planets:Jupiter

Hello! I'm sorry that I didn't write any entries last week. I were very busy because of the university festival. But the university festival were over! Then, I'll write many entries.



In the university festival, I went to the exhibition held by a circle of drawing pictures. There were some pictures about planets in the solar system. And there was such a comment written by someone who drew about Jupiter!

" Jupiter doesn't have much special features."

But, I think, Jupiter has many special features!!! Then, I'll write about Jupiter today!!!!!






Jupiter is the fifth planet from the sun. It is the largest and the most heavy planet in the solar system! It is a giant gass planet. It's composed of gasses mainly. Its mass is more heavy than the total amount of other planets in the solar system(Mercury, Venus, Earth, Mars, Saturn, Uranus and Neptune). It's very very heavy! But its density isn't large. Its density is the third smallest among planets in the solar system.

There is a big red swirl. Its name is "great red spot." Surprisingly, it is larger than Earth! It is like a typhoon. We can observe it with a telescope of over twelve-inch caliber.

Jupiter is known to having 67 satellites so Jupiter has the most satellites in the solar system. But there are possibilities planets have more satellites.

I think "Galilean moons" are famous. Do you know "Galilean moons"? Galilean moons are consisted of Io, Europa, Ganymede and Callisto. They were detected by Galileo Galilei who is an Italien astronomer. We can observe them with binoculars!

Jupiter is also called "cleaner in the solar system." Jupiter have protected innner planets from collisions by comets and asteroids. If it were not for Jupiter, Earth would be impacted 1000 times more than now. Jupiter is indispensable planet to us!


There are more special features about Jupiter, but I can't write all of them. I think Jupiter is a wonderful planet!
