The Saturn Moon Mimas
Mimas is an inner moon of Saturn and is the innermost of the major moons, which are Enceliadus, Tethys, Dione, Rhea, Titan, Hyperion, Iapetus, and Phoebe. Mimas has a crater named the Herschel Crater, which is approximately 88 miles and one-third the diameter of Mimas. The walls of the Herschel Crater are approximately 3 miles high and parts of the floor of the crater range approximately 6 miles deep. The central peak towers of the Herschel Crater on Mimas are almost 4 miles above the floor of the crater. To imagine this crater on Earth, it would be around 4,000 kilometers.
A English astronomer named William Herschel, had been using his 40-foot reflector telescope when he had made the discovery of Mimas on September 17, 1789. The name Mimas comes from the god (or Titan) Mimas in Greek mythology who was slain by one of the gods of Olympus in the war between the Olympians and the Titans. His son, John Herschel, suggested that the moons of Saturn be associated with Greek mythical brothers and sisters of Kronus, known to the Romans as Saturn. This tradition had begun with the publication of John Herschel's 1847 book.
Mimas averages 246 miles in diameter and its shock waves from the Herschel impact may have caused the fractures that were created as a result on the opposite side of Mimas, which many scientists have researched. Mimas shape is not quite big enough to hold a round shape. Mimas is known to be the smallest known astronomical body that is thought to be rounded in shape due to the result of its self-gravitation. Mimas orbits at a range of 115,280 miles from Saturn in a time frame of 22 hours 37 minutes. Mimas’ orbit makes it the closest major moon of all moons of Saturn. Mimas is known to be tida...

...round 84 Kelvin (minus 310 degrees Fahrenheit). This is what I have learned about reading the material that has been based on the moon Mimas.This has been a truly remarkable experience in performing the research on the moon Mimas. I have learned a lot from reading the information on the resources I have gathered completing this research, and from what I have learned from Astronomy 115 with David Jeschke who is an instructor at Pierce College. I hope you have enjoyed reading this and learning some of the things I have learned from creating this research paper.

On the night of October 1, 1847 Maria Mitchell discovered a comet just above the North Star. But by the time her letter of discovery reached William Bond (director of the Harvard Observatory) Father de Vico at the Vatican Observatory in Rome had already announced his discovery of the same comet on October 3. Professor Bond began a campaign to get Maria her rightful award.
Hermes is also known for his many love affairs with numerous mortals, goddesses, and nymphs. In the Odyssey he serves as a messenger and is sent to Kalypso to tell her that she must let Odysseus off her island. The next person, Helios, is actually not a god, but rather a titan. He is the son of Hyperion and Thea and represents the sun, and his sisters Serena and Eos represent the night and the dawn. An easy way to remember him is that “Helios” is a root word from Greek for sun.
To calibrate the thermometer that I bought from Irvine Valley College, I followed the steps given by my Astronomy 20 teacher, Roy McCord. First, I purchased distilled water. I then found a reliable source, to research the point at which water freezes and boils in Celsius. Water freezes at 0°C and boils at 100°C.
Maus is a graphic novel about the Holocaust where all the characters are depicted as animals. Cats are Germans, dogs are Americans, pigs are Polish, and Mice are Jews. The story is told through the eyes of Vladek Spiegelman who is also the author's father. Vladek Spiegelman survived the Holocaust, because of his abundance amount of money and the ability to get on everyone's good side. Maus has many limitations to the story such as point of view, lack of experience, and depiction of characters. Those limitations could be advantages as well as not experiencing the Holocaust means there are no biases towards people or places. Even so, the author wrote his book through the eyes of Vladek Spiegelman.

Neptune was discovered through a discrepancy in Uranus’s orbit. Uranus’s orbit was not moving how astronomers predicted it would. They could not find an elliptical orbit that fit Uranus’s trajectory. They therefore assumed that there had to be another planet that’s gravitational pull was effecting Uranus. Johann Galle was the first to find Neptune in 1846, even though many before him had mathematically predicted where this new planet would be. The planet was named Neptune and two astronomers who had predicted mathematically where it would be are credited with finding it not Galle.

Mercury’s surface temperatures range from -180*C to 450*C (-290*F to 840*F). Temperatures that hot can melt iron, and other metals. The dramatic temperature difference on Mercury are not only because it is so close to the sun but, also by Mercury’s surface features. The places that are the coldest on Mercury and at the bottom of the craters and basins. The hottest are the places closest to the sun.
In 1609, Galileo Galilei, using “spyglass” which allowed one to see things closer than they appeared, made an early version of the telescope. With it, he observed the skies in a way no one had before. He discovered the moon isn’t perfectly globular, it has craters, the Sun has sunspots, Venus orbits the Sun (contrary to widespread belief in his time), and then he observed four “stars” around Jupiter (“Our Solar System”). Within days, he realized that these objects were not stars, they were moons. Io, Ganymede, Castillo, and Europa are known as the Galilean Moons or Satellites, collectively. During the 19th century, the first measurable physical studies of these moons became achievable when Simon de Laplace derived the satellite masses from their shared gravitational perturbations and afterward, other workers used a new generation of telescopes to measure the mass of these moons. The data collected showed that the density declined from the inner to the outer satellites. According to Adam Showman, “More recent observations of water ice on the surfaces of the outer three moons led to the inference that the satellite compositions range from mostly silicate rock at Io to 60% silicate rock and 40% volatile ices (by mass) at Ganymede and Callisto” ( 77). The Voyager flybys of Jupiter in 1979 exposed indication of extensive geological activity like Europa's fractured terrains, which probably result from tidal heating and bending...
Hypatia was born in the year 370 AD in Alexandria, Egypt. She was the daughter of Theon, a famous mathematician and astronomer. He invented many things, but his most famous invention is the astrolabe, which measures the altitude of a star or planet. Hypatia studied with her father for many years at the Museum in Alexandria, but soon became unsatisfied with his instruction because she was smarter than him. She left Egypt, and traveled to Greece and Rome to do "post-graduate" work. Her brains and beauty gave her a wonderful reputation throughout the capitols near the Mediterranean.
Astronomy is a very important field in science. Ancient Greece, China, and India all contributed to our everyday ideas and uses of astronomy. Ancient Greece was the most influential because the Indian’s based most of their astronomy off of Greece. The Greeks created calendars that were based off of the eclipse cycle, which they called by two different names, Hellenic Calendars and Lunisolar Calendars. Because of Ancient Greece, we now have calendars to keep us on track every day. The Greeks observed a celestial object passing through the eastern and western morning sky. After a long time of observations, they came to a realization that it was a planet and now that is the planet is well known as Venus. (Sarton, 75) Plato and Aristotle’s theories were incredible contributions on us today. Both of their theories were all about the behavior and life of the planets, such as their theory that the earth is spherical. (Sarton, 421). Ancient Greece als...
The moon is probably the most noticeable object outside of earth atmosphere besides the sun. There are a great number of facts about the moon. Most of these facts include size and distance of the moon compared to the Earth. Our moon's proper name is "Luna". Luna is 238,900 miles away from earth, and 27% smaller than earth. The moon is the most studied object outside of earths atmosphere. Luna is the only naturally made object that humans have set foot on besides earth.
Located on the planet Mars, Olympus Mons is the largest volcano (and mountain) in the Solar System. It is 17 miles (27km) tall and more than 320 miles (520km) wide
