The Earth and Moon are very different for many reasons, but they are also very similar in some ways. Earth is a planet that orbits a star, the sun. The Moon orbits the Earth and is not a planet. Earth is an “alive” and changing planet, while the Moon is a “dead” and still.
Earth and the Moon have very different surfaces. Earth’s surface changes constantly. Movement of crust, erosion by water and wind, and living organisms all contribute to the changes. Plate tectonics cause the crust of Earth to move around and create mountains and volcanoes. The movement of water can cause re-shaping, and so can the wind when it picks up loose material, they both carve into the Earth. Living organisms change the surface a lot. They build, move and destroy things all the time. The Moon’s surface is mostly still. It doesn’t have a molten core, so there is very little tectonic activity. There is no wind, and the small amount of water is buried in polar areas. There are no living organisms to change the surface either. The only major factor in the Moon changing, is the impact of meteoroids. They form craters when they hit the surface. Lastly, Earth’s surface is very young, because it is changing constantly. The Moon’s surface is hundreds of million to billion of years old.
The two atmospheres are very different also. The Moon isn’t considered to have an atmosphere. It doesn’t have any wind, rain, snow, etc. Earth has a complex atmosphere. It consists of 78% nitrogen, 21% oxygen, 0.9% argon, 0.03% carbon dioxide and very small percentages of other elements. The atmosphere also contains water vapor. It is divided into layers, the Troposphere, Stratosphere, Mesosphere, Ionosphere, and the Exosphere. The weather and clouds are in the Troposphere. The O...

...’s orbital period and rotation period is 27.322 days, which is about how many days there are in a month.
The Moon and Earth both have gravity. Their gravity is different though. Earth’s gravity is 9.78 m/s2. The Moon’s gravity is 1.622 m/s2. The Moon’s gravity is 83.3% less than Earth’s.
Earth and the Moon are also similar. Both are made of rock. Both reflect sunlight. One and the other get energy from the sun. Even though the Moon orbits earth, it still revolves around the sun, just like Earth. They also both rotate. Lastly, they are both heated by the sun.

However Vala mentions that the Sun didn’t have her “hall” yet or know her purpose nor did Moon, noted to be Sun’s companion, know its purpose yet. The Northern Europeans understandably associated the sun and moon together as it appeared that one rose at night and one in the morning and both celestial objects glowed and must’ve held a purpose or influenced life on earth.
Space, a mysterious place, the moon, a curious place that mankind wonders about day by day. In the 1960’s and early 1970’s the United States sent a team of three to the moon for the very first time. The crew consisted was: Neil Armstrong, Buzz Aldrin, and Michael Collins. Out of the three, Neil Armstrong was the first to step foot on the moon (Journal of American History 609). The name of the mission to the moon was called “Apollo 11” this mission took place on July 1969 (Beall, Jeffrey 122). Space is an unexplored place, there are still people trying to discover more than they already know. Curtin people were doubting the mission, some people b the U.S. flag looked like it was flapping in the wind, but the moon does not have an atmosphere (Mashing Moon Myths 505).
Uranus is one of the Jovian planets and like the others it has a short rotation period. Uranus’s day is 17.2 hours. Its revolution around the sun however is slightly more than 84 years. It is the seventh planet from the sun at a distance of 1.78 billion miles.
... 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.

Pluto's rotation period is 6.387 days, the same as its satellite Charon. Although it is common for a satellite to travel in a synchronous orbit with its planet, Pluto is the only planet to rotate synchronously with the orbit of its satellite. Thus being tidally locked, Pluto and Charon continuously face each other as they travel through space.
On May 25, 1961, Congress met in a joint session to hear the American president, John F. Kennedy, address them in a speech he referred to as a second State of the Union. In his speech, the young president geared America for a race that would send men to the moon. Kennedy challenged America to “take longer strides” and to take a “leading role in space achievement, which, in many ways, may hold the key to our future on earth” (Burrows 330-331). America rose to the challenge, and within a decade, Neil Armstrong and Buzz Aldrin were walking on the moon, becoming the first of the human race to walk on a world besides our own. The giant strides of which Kennedy challenged us soon slowed to a crawl, however, and after a few more missions, America would not go back again, possibly for good. America would soon turn its attention to other earthly issues, and its moon program would become nothing more than a memory. This gives rise to an inevitable question: should humans return to the moon? This question has haunted us for years, continuously rising and then fading away again. In recent months, new discoveries have brought it to the forefront, and with these new discoveries, the answer becomes obvious: humans should once again set their sights for the heavens, and putting a civilian lunar base and colony on the moon should be our next step.
There are five basic theories in the formation of our moon. The first is the "fission theory" which states that the moon was once a part of earth, but separated a long time ago. The second theory is called the "capture theory". This theory is says that the moon formed somewhere else, and was "captured" by earths gravitational pull. The third theory is called the "condensation theory" this theory states that the moon and earth were condemned together from the original nebula that formed our solar system. The fourth theory called the "Colliding Planetesimals Theory" states that the interaction between the earth orbiting the sun, and the sun orbiting planetesimals, which are large Astroid like rocks, led to the breakup and formation of our moon from the debris of these planetesimals. The fifth and final theory is called ...
General Description: Earth may be the most unique of all planets because of the life forms we know exist here and the way they utilize the Suns energy. The Earth is composed of a great amount of water, mostly in the form of oceans, which make up most of its surface. It also contains various gases, of which make it possible for us humans to exist and is a system that exists between plants and animals here.
Mars, the beautiful red planet, is the most similar planet to earth. The terrain in general is very close to what we are used to on earth, minus the vegetation. Earth and Mars both contain polar ice caps. Mars also has water throughout the planet, but it is mostly subsoil.
...lieve that millions of years ago, a piece of rock as big as Mars hit the Earth, and the collision blasted a huge amount of rock into space, and the shattered pieces of rock went into orbit around the Earth. Over millions of years, the rocks clumped together to form the moon, and now it is not the pieces of rock that orbit the Earth, but the moon itself. Scientists, Native Americans, and many other people have their theories of how the moon became, but none have been proven. Scientists have studied the moon for many years, and have proven many theories, but not this one.
The atmosphere is an open system that consists of a gaseous mixture enveloping a planet (Answers.com). These gasses, known as air, include O2, N2 and H2O. The atmosphere is also composed of water, ice and dust particles. Atmosphere functions like a blanket, keeping Earth's heat from escaping into space (Lenkeit). It has also been compared to a greenhouse: like glass it lets short wave insulation inside, but keeps most of long wave ground radiation from going out (Lenkeit).
Our knowledge gained of Titan has drastically improved since the early 1980s when Voyager flew past it. Titan is Saturn’s largest moon and the second largest moon of our solar system. It has a diameter estimated roughly 40% of Earth’s moon (Titan’s Radius: 2576, Moon’s Radius: 1737) and is 80% more massive (Titan’s Mass: 1.35 x 10^23 kg, Moon’s Mass: 7.35 x 10^22 kg. Titan has a atmospheric surface pressure 50% more than of Earth’s. In addition to that, Titan is the only moon to have a dense atmosphere. Titan’s atmosphere has been calculated to be 4.5 times more dense than of Earth’s atmosphere, which can been clearly noted by the layers of haze seen. The atmosphere in Titan is approximately 1.5km and is mainly composed of nitrogen. Titan has a very similar vertical atmospheric structure to earth, Titan has a troposphere temperature of ~94-~70K, a tropopause temperature of 70.4K and a stratosphere temperature of ~70-175K.
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.
First, according to NASA, the Earth possesses a moderate pattern of temperature. Second, the article also states, the Earth rotates around its axis, which is tilted 23.5 degree, to result in the change of day and night. Furthermore, it also moves around the Sun, so that we have different seasons. After that, NASA indicates that one of the most important factors for life to exist on this planet is the magnetic field caused by its spin and materials lying in the core. Alternatively, the planet is protected by the ozone layer, which is able to prevent its collision with other meteors from the outer space. Nonetheless, there are a variety of elements which may influence the life on Earth, such as volcanoes, tectonic activeness and so on. Overall, NASA realizes that Moon plays the role as the satellite to protect the Earth as well as causing various natural
