Jupiter,
or also one of the Jovian planets (gas planets) in our solar system.
Name:
It got its name from the Roman god Jupiter, who also is Zeus in the Greek Mythology. He is the king of all the gods, the strongest, smartest, etc. that can be referred to Jupiter’s size as the biggest planet in our solar system. Also Jupiter is the son of Cronus (Saturn).
The sign stands for the Greek letter “zeta” or “Z” in English which stands for Zeus who is also known as Jupiter.
Discovery:
It was discovered by the Babylonians, but because Jupiter is visible to the naked eye on the night sky, it has been visible to everyone and everything.
Size:
- Diameter: 142,984 km. (11.2 times bigger than Earth’s)
- Mass: 1.9 x 10e27 (317 times more than Earth)
- Density: 1.326 g/cm3 (that means that in case you would put Jupiter in a huge bowl of water it would slowly sink.)
Rotation & Revolution:
Rotation: 9h 58m
Revolution: 11.78 Earth years.
Location:
- 5th planet away from the sun
- 5.2 AU (777909600.9 km)
Land:
- Never solid (gas planet)
- The „sea is out of liquid hydrogen
- 71% hydrogen 24% helium
- About -110 degrees Celsius
- Core is probably solid iron (reason for its enormous magnetic field)
Atmosphere:
· 75% hydrogen 24% helium
· Clouds are out of crystal ammoniac
The Great Red Spot (GRS):
- Discovered in 17th century (350 years!!!)
- High pressured hurricane
- Average wind speed of about 640km/h.
- Twice as big as Earth
- Oval shaped
- 12000km x 25000km area
- more storms (e.g. Little Red Spot)
Rings:
Jupiter has one ring, which has 3-4 parts (Halo Ring, Main Ring, Gossamer Ring/s) depending on your opinion. Some scientists define the Gossamer Ring as one ring others split it up into the Amalthean Gossamer Ring and the Thebe Gossamer Ring. As shown in the picture there are 4 moons orbiting in the ring.
Moons:
- 63 moons (named after Zeus’s lovers)
- 4 Galilean moons (Io, Europa, Callisto, Ganymede)
| Io | Europa | Callisto | Ganymede |
| Most active volcanic body in our solar system (100x more than Earths) | Has a 100km deep water-ocean under its surface. | Has very old craters, that give details about the earlier universe | Biggest moon in the solar system (bigger than Mercury) |
Important Missions:
- Pioneer 10 (first to pass the Asteroid belt, Jupiter Flyby, still travelling)
- Pioneer 11 (2nd to pass the Asteroid belt, Jupiter Flyby, helped to study the moons, magnetic field, atmosphere, broke but still travelling)
- Voyager 2 ( Jupiter Flyby, discovered the rings of Jupiter)
- Galileo (Jupiter orbiting mission, first to put a probe into an outer planets atmosphere, helped to observe the atmosphere Ingredients and then the Galilean Moons in more detail.
- JUNO (Launching in August this year, going to polar orbit Jupiter)

Hi Val!
ReplyDeleteThis is a big improvement! You had a nice video, you had lots of information about missions to Jupiter, and you explained the moons very well. Some things you cuold change are having more than one color, another picture, check grammar, and things like that. Your science is very very good! For your link to your notes, you should have a direct target link to them or at least to the Science Moodle page, not just to Moodle's homepage. Other than that, I really liked this post and having a table was a great idea! Keep it up! :)
Val - This was turned in on time and included majority of the information you presented in class. Your spelling and punctuation look great, but you have a few grammatical errors, and I think you could have used more than one color and maybe less bold to help your reader be able to follow the formatting better of your post. Your link is to Moodle in general, and I think it could be more specific (8th grade at least and one more to your notes). Your other link is interesting, but is not very informative. I do like your ring picture, but I think you could have included more pictures throughout out the post to help the reader be able to visualize what you were writing about. Overall, nice writing improvement, but I do think more media could have been used to "spice" up the post. ~Ms. D.
ReplyDeleteHey Val,
ReplyDeleteYour post overall was very good and in my opinion, better than your last one. Your writing is clear and relatively easy to read. However, I think you could've added more links to relavent sites or videos, as well as added more images. You also had a few grammatical and spelling errors, but they did not detract from the overall competency of your post.
Hi Val
ReplyDeleteI really liked your post about Jupiter. There are some good parts and some bad parts to your post. First the good parts. It is nice that you put all of the scientific numberes about your planet. The pictures where helpful and all have captions. You could have added some colors to your post because it looked a little dull. It is good that you put a video on but it was not usefull. I did not see a link to Moodle. Also some of the writings had weired fonts in front of them. Overall it was an intresting post.
