The moon
The moon is the only natural satellite of Earth. The moon orbits the Earth from 384,400 km and has an average speed of 3700 km per hour. It has a diameter of 3476 km, which is about ¼ that of the Earth and has a mass of 7.35e22 kg. The moon is the second brightest object in the sky after the sun.
The gravitational forces between the Earth and the moon cause some interesting effects; tides are the most obvious. The moon has no atmosphere, but there is evidence by the United States Department of Defense Clementine spacecraft shows that there maybe water ice in some deep craters near the moon's North and South Pole that are permanently shaded. Most of the moon's surface is covered with regolith, which is a mixture of fine dust and rocky debris produced by meteor impact. There are two types of terrain on the moon. One is the heavily cratered and very old highlands. The other is the relatively smooth and younger craters that were flooded with molten lava.
Throughout the 19th and 20th centuries, visual exploration through powerful telescopes has yielded a fairly comprehensive picture of the visible side of the moon. The hitherto unseen far side of the moon was first revealed to the world in October 1959 through photographs made by the Soviet Lunik III spacecraft. These photographs showed that the far side of the moon is similar to the near side except that large lunar maria are absent. Craters are now known to cover the entire moon, ranging in size from huge, ringed maria to those of microscopic size. The entire moon has about 3 trillion craters larger than about 1 m in diameter.
The moon shows different phases as it moves along its orbit around the earth. Half the moon is always in sunlight, just as half the earth has day while the other half has night. The phases of the moon depend on how much of the sunlit half can be seen at any one time. In the new moon, the face is completely in shadow. About a week later, the moon is in first quarter, resembling a half-circle; another week later, the full moon shows its fully lighted surface; a week afterward, in its last quarter, the moon appears as a half-circle again. The entire cycle is repeated each lunar month, which is approximately 29.
Fifteen years before Neil Armstrong stepped foot on the moon, one of Belgium’s most successful bande dessine´e which is a specific type of artist named, Herge, sent his “hero” named Tintin to the moon in his book called Destination Moon (Beauvais,PClementine 252). In the human mind the moon can be interpreted as many different things. For example, some may think the moon is a god, Heaven, Hell, or sometimes even as a whole other Earth (Springer 252). When Herge was born at the beginning of the twenty century a piece of literature called From the Earth to the Moon written by Jules Verne’s was possible where the ideas of the moon stem from (Goddin 100). NASA is planning on sending humans back to the moon in a mission called “solid beginnings” in the future. For the past three decades the moon hasn’t been the main focus with all of the other planets such as: Venus and Mars (Lawer 612).Some people believe that the core of the moons material raised up and went to the sur...
In the beginning of the creation of Earth volcanoes erupted all over the planet. During this period there was a time where a brief cooling period was allowed to take place. When this period took place evaporation caused a downpour of rain which flooded the ocean creating the ocean. At the time that ocean was averaged at 3,000 degrees Fahrenheit. Around this same time an asteroid so powerful hit the Earth knocking off a large chunk of it. This chunk became the moon which at the time was twice as close as it is today. The hitting of the planet Earth cause such a shake that many new undersea volcanoes began spewing forth molten rock and gasses. These gasses and other particles formed on the oceans surface and with the moon being so close were smashed together by strong and violent waves.
The moon has many phases and you will get to know them all. You will discover the connection between the moons’ phases and the relative positions of the moon, Earth, and sun. You will explore how the moon’s illuminated surface seems to grow and shrink over the course of a month. You will learn the difference between crescent and gibbous, and follow the moon’s journey from new moon to full moon and back again.
... sticks. When the activity is done it leaves a hardened textured surface and you can see bits of yellow showing through. During this activity you can discuss the different shapes of the moon, where the moon light comes from and what the moon is made of.
Still, I believe the moon does affect us. Put me in a storm cellar, I'll guess when the moon's at apogee. It’s that feeling you get on a rolly coaster, the momentary pause at the top of the hump before all that stored kinetic energy is released and you plummet over the precipice.
Though the average movement of the Moon around the Earth depends for the most part on the gravitational attraction between them, it is somewhat decreased by the draw of the Sun on the Moon. This sun based activity depends, nonetheless, on changes in the eccentricity of the Earth's orbit coming about because of irritations by alternate planets. Thus, the Moon's mean movement is quickened as long as the Earth's circle has a tendency to be more roundabout. The disparity is along these lines not really aggregate, Laplace resolved, but rather is of a period running into a huge number of years. The last danger of flimsiness in this manner vanished from the hypothetical depiction of the solar
The surface of the moon is scarred with millions of impact craters. There is no atmosphere on the moon to help protect it from bombardment from potential impactors (most objects from space burn up in the Earth's atmosphere). Also, there is no erosion (wind or water) and little geologic activity to wear away these craters, so they remain unchanged until another new impact changes it. These craters range in size up to many hundreds of kilometers, but the most enormous craters have been flooded by lava, and only parts of the outline are visible. The total area of the moon is 37 930 000 square kilometers.
7.349x10^22 is the mass of the moon in kg and 1.7381x10^6 is the radius of the moon in meters. On the moon objects experience roughly 1/6 the gravitational force they would on Earth.
We also calculated the density of a moon based on its make up or rock and ice percentage. We use the formula ( (P rock) (3.5) + (P ice) (0.9) ) / 100. When the moon is 100% rock and 0% ice, the moon’s density is 3.5 g/cm^3. When the moon is 80% rock and 20% ice, the moon’s density is 2.98 g/cm^3. When the moon is 60% rock and 40% ice, the moon’s density is 2.46 g/cm^3. When the moon is 40% rock and 60% ice, the moon’s density is 1.94 g/cm^3. When the moon is 20% rock and 80% ice, the moon’s density is 1.42 g/cm^3. When the moon is 0% rock and 100% ice, the moon’s density is .9
Upon embarking from the module to the moon’s surface both Armstrong and Aldrin, begin providing scientists with a description of the landscape, rocks, and gravity of the moon. Cohn states that both astronauts reported various craters formed by meteorites to scientists at NASA.O’Toole,
With the help of Anemoi, the Zeus made the moon orbit earth. They thought that it would bring earth night and day. But it didn’t. The moon crashed into the sun. The gods then had to use one moon and sun from the five left by Nyx and Hemera.
As it turned out, we learned a lot from those missions, there was much more to it than just getting a man on the moon. We learned that the moon and the earth were very similar when it came to composition but there are enough differences that its formation can't have come from earth alone, the commonly accepted theory is called the gigantic impact theory, which explains the moon's formation by asserting that a celestial body, nearly half the size of the earth, hit the planet and cause the moon to break off and begin its orbit around the earth around 50 million years after the formation of the earth.
One of the areas I could identify during this observation was the Tycho. This was a interesting feature which looks like fireworks. Tycho is smaller than Copernicus and it is also relatively young in lunar terms, 108 years old. A dark ring surrounds Tycho which according to different studies, including one that landed on the crater, indicate the dark material is glassy impact-melted rock, scientist belief that a meteorite fell and during the impact and explosion occurred forming the crater.
The moon is a wondrous thing. Every night it's outside, up high in the sky, giving light to the world. Most people take advantage of the moon's light, because they don't know why or how the moon shines. Scientists today are busy proving theories and studying the moon, which will hopefully help society to understand the moon more. They know a lot about the moon, but there is still much more to learn.
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.
