The Effects the Moon has on Earth As the moon dances along its orbit in uniform motion with the earth, we see it going from a new moon to full moon and back. We normally think that the moon has no effect on us whatsoever, but in reality, we wouldn’t be where we are now without the moon. The effects the moon has on the earth are ocean tides, the length of our day, months, and animal behavior. The moon tries to pull the earth closer with its gravity. But with the earth being three times more massive than the moon, it is able to stay in place.
The origin of meteorites has been linked to the moon, and Mars, while the rest of the “meteors” are believed to be fragments originating from asteroids, comets, and other planetary debris. (Hamilton, 2009) Comets are composed of ice and dirt that gets stripped away from the nucleus by solar winds as the comet nears the sun. This causes the comet to form a tail that
The Geology of the Moon Approximately 4.5 billion years ago a large asteroid struck Earth and thus resulted in the Moon. This impact theory suggests that the collision ejected raw materials which in time became the Moon. With the Moon having no significant atmosphere, it can reserve a good record of the impact history. This information can provide geologists with clues to the history of the Earth. The crust of the Moon is composed of a variation of primary elements, including uranium, oxygen, thorium, potassium, silicon, magnesium, iron, titanium, calcium, aluminum and hydrogen.
Phobos will eventually crash into Mars or break up and form a ring around the planet. Deimos (which means fear) was named after the Greek God Deimos who was the twin brother of Phobos. Deimos is the outer moon so it is further away from Mars and takes about 30 hours to orbit. It is small and lumpy and has lots of craters and is covered in dust and loose rocks. Although it has many craters it’s surface is much smoother than Phobos’ Deimos has an average radius of 6.2
Saturns Moons The planet of Saturn is an amazing planet as far as moons go. This planet is currently known to have fifty-two moons. Some of these moons are spherical in shape much like Earths moon and some look to be no more than a meteor that was captured by the huge planet. Now Im not going to be able to discuss every moon that belongs to Saturn but I will talk about the six biggest which are: Titan, Rhea, Iapetus, Dione, Tethys, and Enceladus. All of Saturns moons were named after Greek Mythological figures.
Writing in the journal Nature, David Charbonneau at the Harvard-Smithsonian Centre for Astrophysics describes how his team used a suite of eight amateur-sized telescopes to spot the planet as it moved across the face of its star, which is less than 0.5% as bright as our own sun. The telescopes picked up a slight dimming in light from the star as the waterworld, named GJ1214b, passed in front of it every 1.6 days. The planet has a radius 2.7 times as large as the
Meteorites likely traveled in space for millions of years before visiting us here on Earth. They were bathed in cosmic rays, but are not dangerous or radioactive. If your rock looks just like other Earth rocks, it probably is one. Meteorites look and feel different from the ordinary rocks around them. Recently fallen
We wouldn't live nearly as long as we do without them. The same goes for the discoveries of the solar system. It is impossible to rand their importance, so they are listed in the order they were discovered. The first time humans have ever discovered a planet was in the 2nd millennium BC by the ancient Babylonian astronomers. Soon, Aristarchus of Samos, and later in Nicolas Copernicus' heliocentric system that he published in 1543, the Earth came to be considered a planet revolving with the other planets around the Sun.
Some students believe that the Earth’s tilt changes in degree as the seasons change and that the axis points in different directions as the Earth orbits the Sun. In reality the Earth’s axis is always tilted at 23.5 degrees and the North Pole always points toward Polaris (Lambert, 2010). Most of the planets in the solar system have nearly circular orbits, much like Earth. The orbits do, however, have an elongated shape. The orbits of Mercury and Pluto are very elongated whereas the orbits of the other planets are almost circular (Nelson, 2005).
It is called an orbiter because it will orbit, or circle, the fourth planet from the sun. Right now, the orbiter is speeding toward Mars. Scientists expect it to reach the Red Planet in March. The orbiter will join two robots, called rovers, that are already there. They have been rolling around on the surface of the planet for more than two years.
