Comet Shoemaker-Levy 9


Sumarry
Comet Shoemaker-Levy 9 was a comit founded by astronomers Carolyn and Eugene M. Shoemaker and David Levy. It was discovered on March 24, 1993 near Jupiter. The comet was observed over a period of time as it orbited Jupiter. During the observation of this comet the astronomers realized that the shape of the comets orbit was changing and eliptical. At some times more than other it would become pulled closer by the forces on Jupiter. At one point in its orbit on July 16, 1994 Shoemaker Levy 9 ventured to cloose to Jupiter in its orbit and enterd Jupiters roche limit where the forces around jupiter pulled the comet into the roche limit and broke the comet into 21 seperate pieces. Over the period of 6 days, the 21 pieces of Shoemaker-Levy 9 impacted have all impacted into the sides of Jupiter. No part of the comet still exsists. (There isn't very much known information on this comet because it was only around for little over a year and we were never capable of sending any probes or anything to further investigate what we could see through a telescope and gather from that information.)

Accuracy:
This site has a lot of good and usable information. There are other sites which state different amount of pieces or estimated size of the pieces after
the comet broke up. Wikipedia is a site which allows anyone at anytime to change and add any information they want to a page so you must be
hesitant when using information off of wikipedia.

Readability and Clarity:
This website is pretty easy information to access for adults and students doing research projects or having an intrest in astronomy. To undertsnad the information posted on the website students or general people would need atleast a minimal level of education and some decent background knowledge on astronomy.

Ease of Navigation:
Wikipedia is a pretty easy site to use. It has a lot of information on all levels of a topic and has links on words or other phrases to take you to pages or definitions incase someone doesn't understand any of the information.

Accuracy:
The accuracy of this website is pretty reliable and agrees with most other websites with information on Comet Shoemaker-Levy 9. The information found on here is pretty correct but there also isn't very much information listed on this website compared to others like Wikipedia.
Readbility and Clarity:
This website is pretty easy to read and contains other links to take you to external pages or websites to help you understnad words or find more information if this website didn't contain all that you needed. It's good for any astronomer or student, but not very child friendly.
Ease of Navigation:
Nine planets is a pretty good site. It hzs been around for a long time and all the information seems to be very reliable as it matches with other places. I just think it would be better if it contained more information on this topic.

Accuracy:
The only real information on this website is about a sentence or two that talk about the collision with Jupiter after the comet broke up into pieces. The information is correct but there isn't very much and any other information you want, you must go through a ton of links listed on the rest of the page.

Readability and Clarity:
The website contains accurate information but doesn't contain very much information. It seems to be more of a page for links to other pages related to the topic.

Ease of Navigation:
In my opinion, this isn't a website i'd probably use unless I needed to find information for a different topic than the two sentences listed about the collision because it's full of links on other aspects about the comet.

Accuracy:
The information listed on this page seems to be pretty accurate and agrees with all other sources i've found which have all been reliable. The only thing is theres not really knowledge of when it was last updated and how up to date the information could or couldn't be.

Readability and Clarity:
The information posted on this website is pretty easy to read and is very clear on what they are trying to say. Also, it is easy to read as it is broken up in different sections so you don't really have to go searching if you are just looking for information on something specific pertaining to Shoemaker-Levy 9.

Ease of Navigation:
In my opinion this website is a good second choice website. The website seems to contain all acurate information but it doesn't have the largest amount of information out there, but on the other hand, it does have a group of good pictures of the comet and its impact which some I have been incapable of finding anywhere else.

Accuracy:
Though the title on the page is a little misleading, it is only the answer to one question, not frequently asked questions. The information provided to answer the question is accurate though as it matches up with all the other sources found.

Readability and Clarity:
This web page is easy to read and seems to have language which should be understandable to most every student and adult. It offers great pictures with captions of what is in each picture that retains to the information the author stated in the writing just below the pictures.

Ease of Navigation:
I think this website is on the lower side of good websites as it says its for frequebtly asked questions, but there is only one question and one answer and I know through my planet report there was more questions asked other than just about if it did colide with Jupiter or not. On the other hand, the information provided for that one question seems to be pretty accurate which was good and I like how he had captions on his pictures to further explain what you were looking at and they connected to what you were reading.
