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.

The moon is mentioned abundantly in the scripture, many researches say the phases of the moon have a direct relationship with what occurs around the world. Judy Isacoff writes "The phases of the moon are a significant part of our experience of life on Earth." According to NASA, one ...
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.

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.
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.
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.
The moon is very slowly drifting away from the earth. Currently, it is at a distance of approximately 239,000 miles away from the planet's surface and receding at a miniscule, but steady rate. However, "if one multiplies this recession speed by the presumed evolutionary age, the moon would be much farther away from the earth than it is, even if it had started from the earth. It could not have been receding for anything like the age demanded by the doctrine of evolution." (Barnes) Furthermore, even if the moon had started much closer to the ea...
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).
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.
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.
?The Eagle has landed.? Many people use this phrase without knowing where it came from. On July 20, 1969, NASA astonished the world, when Neil Armstrong spoke these words when the Apollo spacecraft, nicknamed ?the Eagle,? landed on the moon?s surface. He later spoke the famous words, ?One small step for man, one giant leap for mankind,? when he was the first man to set foot on the moon. When astronauts walk on the moon, they are allowed to breathe, because of their space suits. These space suits have oxygen tanks in them, and allow astronauts to stay out in space for up to seven hours at a time. They have to think ahead a few steps so they can step or turn without difficulty, because they have to take huge steps. The pull of gravity on the moon is one-sixth lower than the pull of gravity on the Earth, which makes them a lot lighter on the moon. The moon?s gravitational pull controls the ocean?s tides on the Earth. The moon pulls the Earth and water towards it, which causes an increase of water nearest the moon. As the moon pulls the core of the Earth towards it, the water on the side farthest away from the moon flings around to the side, and creates an increase of water there, too. The increase of water is called a high tide. On the sides of the Earth not facing the sun or moon, there are low tides. Each beach or po...
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.
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.
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
