JUPITER:  "EPIC-NESS" IN A PLANET FORM
Hey, this is Jack at my epic blog! I am going to talk about ...well, come on!  What's the title?  Anyway, time for the "epic-ness" to start. 
 
The planet Jupiter is named after the Roman god Jupiter, who was the king of the Roman gods:





It makes sense to name the planet after the king of the gods because Jupiter is the largest planet in our solar system.  It's truly massive.  More than 1,000 Earths could fit inside Jupiter!  Here's a visual.  The big planet is Jupiter, and the tiny blue planet next to it is Earth:



 
This massive size is the reason the gravity on Jupiter is the strongest in our entire solar system.  The gravity on Jupiter is about 2.5 times what it is on Earth.

Jupiter is the fifth planet from the sun. 




Here's a picture of Jupiter.  This picture is epic because it's actually a true color picture of Jupiter:




Jupiter is a gas-giant planet.  It doesn't have a solid surface.  Gas-giant planets are called "Jovian" planets (Jupiter-like).  There are four of them:  Jupiter, Saturn, Uranus, and Neptune.  The inner planets are not gas-giants.; they're called "terrestrial" planets.  They're mostly solid, and they include Mercury, Venus, Earth, and Mars.

Scientists think that Jupiter has an inner, solid core that is about the size of the Earth.

Jupiter's atmosphere is made up mostly of hydrogen and helium. 

Jupiter has a giant red spot on it, called the "Great Red Spot," or "The Eye of Jupiter."  Here it is: 




This "spot" is not a spot at all.  It's actually a humongous storm.  I mean really humongous.  The storm itself is about the size of two or three Earths!  This storm has been going on for hundreds of years!

Jupiter has many, many moons.  Fifty moons are known.  There are 17 more moons that are waiting to be confirmed as actual moons.  For those of you who hate addition, that's a total of 67 moons!


One of Jupiter's moons is called Europa.  Here's a truly epic pic:



Europa is an icy moon.  The surface contains many cracks in the ice.  It's a little bit smaller than the Earth's moon.  Scientists think that Europa has some qualities that are similar to Earth:  an iron core, a rocky mantle, and a surface ocean of salty water.  Can you believe that?  The problem is, this ocean is so deep that it covers the entire surface of Europa.  Because Europa is so far from the sun, the surface of the ocean is basically frozen over. 

The ocean may not be frozen solid, however.  Recently, the Hubble telescope captured a picture of a puff of water vapor that was spouting about 125 miles above the surface of Europa.  Here's an artist's interpretation of what it looked like:





Even though it's frozen on the surface, the water spout supports the theory that the water underneath may not be completely frozen.  This is because the friction created by Jupiter's gravitational pull on Europa generates some heat.  It's water may have the right chemistry to sustain some very basic aquatic life.


Five interesting facts about Jupiter:
(1) If you think about the sun as being the size of a regular front door, in comparison, the Earth would be the size of a nickel, and Jupiter would be the size of a basketball!
(2)  Many space missions have gone to Jupiter.  There's another one scheduled to take place in 2016.  It's called the Juno mission, named after the Juno probe.  Here's a pic:



(3) Another word for Jupiter is "Jove."  That's why scientists refer to things about Jupiter as "Jovian." 
(4)  It takes Jupiter only 10 hours to rotate on its axis, compared to 24 for Earth.
(5)  A year on Jupiter lasts 4,333 days, or about 12 Earth-years!


That's all about Jupiter.  Thanks for reading my blog.
