Trophy Showcase:
Professor Harrington smiled as she finished setting up the projector for her second years lesson. She heard a few voices waiting outside so she let the students in and waited until all seemed to be in the class. “Kia ora katoa*, hello all, how are you all doing this week?” Professor Harrington asked getting a mix of responses back, some picked to not even answer at all. She didn’t mind, she knew for some the late night class was not the most exciting time to have a class, but she liked that they never were scheduled an early morning class after her lessons. “This week is the outer planets, so the gas giants and tiny Pluto!” She said tapping the projector so the information of Jupiter appeared at the front similar to last week. She continued to read out the information at a nice pace so the students had time to take notes.


A few facts about Jupiter: This is the largest planet in our solar system. It is visible in our night sky with the naked eye, appearing to shine like a star in our Sun’s light. It is the fifth planet from the sun and about 318 times larger than Earth. It is twice larger than ALL the other planets combined. It has an equator that is 11 times wider than the Earth. Jupiter has the most circular orbit out of all the planets however because it is so far away, it takes 12 years to complete one rotation around the sun.

A few facts about Saturn: Saturn is the 6th planet from the sun. It is smaller than Jupiter but its rings are a vision to witness. It is the second largest planet in our solar system another gas giant. The rings are a mix of rocks and ice debris left over from the formation of the planet and it's moons.

A few facts about Uranus: The seventh planet from the sun is a lovely blue color. It is the 3rd largest planet in our solar system. It takes 84 years to orbit our sun. The planet itself orbits on a tilt far greater than any of the other planets, in comparison to us. It rotates as if it might have been knocked over. The rings around the planet reflect this rotation as you can see in the picture. The rings are much fewer and less brilliant than Saturn’s rings.

A few facts about Neptune: Named after the God of the Sea. One can see why, it has a wonderful deep blue coloring. Neptune has a fairly fast rotation, days are much shorter there only about 18 hours, as Neptune is just made of gaseous material. Very faintly you can see bands in the atmosphere similar to how Jupiter has bands, however for Neptune the bands are all a similar blue coloring. Neptune does have a fairy faint collection of rings as well.

A few facts about Pluto: Pluto was discovered by accident in 1930 by Clyde William Tombaugh. Pluto is named after the Greek god of the underworld. The name was suggested by an 11-year-old witch from Oxfordshire, England. Pluto has five known moons. Pluto is one third water, all frozen of course. The orbit of Pluto is different from the other planets as it is on an angle differing from the flat plane the other planets follow.

Professor Harrington finished the lecture with a sigh of relief, hopefully the following week wouldn’t be so long. She waited as the students finished their notes before continuing on for the week. “Alright, that is going to conclude our discussion of planets, if you ever have any questions feel free to come to my office hours and ask. Homework is on the board, please complete and turn in by the next lesson, have a good night!” She said dismissing the class.
This Week:
*Kia ora katoa means Hello All in the Native New Zealand Language, Maori.
Please post with your student role playing the lesson!
Homework: Write a short essay about any planet with information not provided in class. (Please make sure to have your source listed once again and by this I mean the website you(ooc) are using for your character!)

Upon taking a seat at her desk in the Astronomy classroom, Harper immediately started to get out her notebook and a pencil. She was pretty sure they would be going over the rest of the planets today. After all, there wasn't much else left in the solar system aside from the asteroid belts. Her guess turned out to be right as Professor Harrington fired up the projector and started to lecture on the outer planets.

Most of the information wasn't particularly new or exciting. But she was surprised to hear that an 11-year-old witch had suggested Pluto's name. Harper wonder how that had happened, but Professor Harrington didn't elaborate. The rest of the class passed without incident. Unfortunately, they had homework though it didn't sound that bad. Just kind of boring. She would have much rather built another clay model of the solar system. Harper copied down the assignment before gathering her stuff and leaving the classroom.

Saturn​

Saturn is the second largest planet and is about 1.4 billion kilometers from the Sun. It takes about 80 minutes for the light from the Sun to reach Saturn. Saturn is one of the gas giants and is mostly made of hydrogen and helium. At its center are metals including iron and nickel surrounded by a rocky material. Saturn is less dense than water, which means it could float if someone found a large enough body of water. It has over 60 moons, and its largest moon is named Titan. One day on Saturn lasts 10.7 hours and one year on Saturn is about 29.4 Earth years.
