The Planetary System Of The Earth And Moon

238,900 miles away, the earth’s moon is one that is truly unique. With a given age of about 4.5 billion years the Earth serves a major role in real life and in the book Life as We Knew It by Susan Beth Pfeffer. When catastrophe strikes, Earth takes a turn for the worst and great natural disasters occur. Thousands die, but there are a number of survivors. If there are survivors, how beneficial is the moon actually? What would happen if the moon had been destroyed? How necessary is it for human survival? The Moon, is a great benefactor to human survival because of the benefits earth gets from it.

and sediments has shown something incredible. It contained clues to how Earth and the Moon formed as well as the history of the Sun. The scientists looked for what life would be like if humans could live on the moon. The Apollo 11 mission brought back the first geologic samples from the Moon back to Earth. Astronauts collected twenty-two kilograms of material which acquired samples of the lunar "soil," fifty rock samples and two core tubes which was found below the moon’s surface. All the samples was not composed with any water which provided no evidence for living organisms in the Moon's history. They figured out that there was volcanic activity since they

The origin of the Moon is, with quite certainty, one of the most bewildering matters that scientist still attempt to uncover. Although there is a certain theory that is currently favoured, Wizard and Muggle Astronomers from throughout the world are aware that this mystery is still not yet fully uncovered.

The most favoured theory on the genesis of the moon that serves as a satellite to the Earth is the Theia Impact Hypothesis. When the early solar system was forming in the first 100 million years after the dust cloud began to coalesce, along with the recognized planet that survived until today, there were other proto-planets forming and orbiting our common star, the sun. Many of these proto-planets were ejected from the solar system, or else crashed into larger proto-planets, either destroying both in the process, or melding into one larger proto-planet. One of these theorized proto-planets was a Mars sized rocky body, known as Theia, which shared the Earth's orbital path.

In 1975, two scientists by the name of Dr. William K. Hartmann and Dr. Donald R. Davis, came up with a groundbreaking new theory on how the moon was created. Their theory stated “At the time Earth formed 4.5 billion years ago, other smaller planetary bodies were also growing. One of these hit earth late in Earth 's growth process, blowing out rocky debris. A fraction of that debris went into orbit around the Earth and aggregated into the moon” (Hartmann & Herres 1). This theory is known as the Giant Impact Theory and is the accepted theory in the scientific community of how the moon was created. Even though this theory is accepted by most, there are still some people who don’t hold this theory to be true. I agree with Davis and Hartmann’s Giant Impact Theory that a great collision occurred and created the moon. The Giant Impact Theory is supported by the lack of iron on the moon, the moon rocks from the Apollo missions, and its acceptance in the scientific community.

The moon is by far the biggest and most easily recognizable object in earth’s atmosphere that can be perceived by the naked eye on a cloudless night. It is hypothesized that it came into existence nearly 4.5 billion years ago, from residual debris after a planetary body collided with earth. Although, considered the runner-up to the sun as the second brightest object in the sky, its illumination is deceitful, insomuch as the moon is not a source of light, but instead reflects the sun’s illumination from the half of the moon that is in direct alignment with the sun at that time. More readily identified as a satellite of the earth rather than as a planet itself or even a star, it has a diameter a quarter of the size of earth’s size and it

Rather than examine each moon separately I’m going to examine particular morphological aspects of all four at the same time for comparative purposes, after a quick introduction to the basic aspects of each

One primary goal of space exploration is astrobiological. Using lunar geology to determine the conditions of the early

The exact origins of the moon are unknown however there are many plausible theories. The most widely accepted theory is known as the giant impact hypothesis. This suggests that the moon was created during a collision between a young Earth and a Mars sized object over four billion years ago. As the two bodies collided they fused whilst simultaneously ejecting debris which combined and formed the moon as we know it.

Mars orbits at a distance of 1.52 AU from the Sun. Mars has two natural satellites, discovered by Asaph Hall in 1877. The innermost of these, Phobos, is about 22.2 km in diameter (27.0×21.6× 18.8) and orbits the planet with a period far less than Mars 's period of rotation 7.7 hr. (only one quarter that of Deimos), causing it to rise in the west and set in the east(Born & Duxbury 1975). Thus, it makes more than 3 orbits in a single Martian day. As it orbits, it slowly spirals in towards the Martian surface. Phobos is drawing closer to Mars by 2 meters every one hundred years, and it is predicted that it will collide with the planet /or destroyed in the atmosphere. Phobos has a semi-major axis 9376 km (2.76 Mars radii), eccentricity 0.0152 and orbit mean inclination 1.1o (relative to Mars’ equator).

Also, the moon has a very interesting history. The moon has no air, water, or life on it. Ancient people had some very odd ideas about the moon. Some of them thought that the dark spots that are on the moon was a man in the moon. Others thought that it could be a woman. Some of them even thought that the moon had mysterious or romantic powers.

Due to its size and composition, the Moon is sometimes classified as a terrestrial "planet" along with Mercury, Venus, Earth and Mars.

The objective of this investigation is to disprove the following set of hypotheses provided in the Task brief where they were collected from Moon Misconceptions (2013):

The most popular theory of the moon's origin is the giant impact theory; this theory is that a giant mars sized space rock struck young earth and knocked a chunk of it out. This theory proves to be fallacious because, no scientist knows where that mars sized rock is; however, the earth and the moon are made with very similar elements (Editor).

This article provides a brief introduction to the types of geological feature to be found on the Moon, to assist in any comparison with other planets and to help the reader decide whether there are any topics they would like to investigate further.
