Mercury: The Creation Of The Caloris Basin

Mercury is like a large rock. Its surface geology is quite similar to Earth's moon. It has many craters from ancient impacts, and also basins and plains. Some of the craters have filled with lava from the planet's interior, and have become lava plains as a result. Boulders and dust from pulverized rock are found on the surface. There are no rivers. The Mariner 10 and Messenger missions sent back many pictures of Mercury's surface, so we know that there is no weather there to affect the surface. From a geological standpoint, Mercury is identified as a planet that has been long dead. Even though it has not been completely mapped by cameras, scientists studying Mercury believe that its surface has not changed for billions of years.

Mercury's most prominent feature is its surface geology. It's almost like the moon, with extensive mare-like plains and heavy cratering, showing that the planet has been geologically inactive for billions of years. Craters range in diameter from bowl-shaped cavities to multi-ringed impact basins hundreds of kilometers across. One of the largest crater is the Caloris Basin, with the diameter of 1,550 km. The impact was so powerful that it caused lava eruptions and a concentrated ring over 2 km tall surrounding the basin to form. There are two distinct regions of plains on Mercury. These plains occur between the crater impacts and they bear a strong resemblence to the lunar maria. From the MESSENGER spacecraft, we were able to see that there

The planet's atmosphere is also surrounded by thick, acidic, sulfuric clouds. The atmospheric pressure is approximately 90 times that of Earth, and the atmosphere is made up mainly of carbon dioxide, with the remaining 3.5% taken up with nitrogen and a few other elements. The thick sulfuric clouds surrounding the planet make it difficult to view the surface with any accuracy, and the huge pressure and heat below the clouds mean that the atmosphere is not conducive for human-made crafts to survive in the climate. Venus's atmosphere is in constant circulation of the planet, circling it in a mere 4 Earth days. The winds near the atmosphere of Venus are approximately 220mph in order to facilitate this speedy atmospheric rotation, although the winds on the surface are much much slower. In summary, Venus would be a bad (and unpleasant) choice for human habitation, due to enormous levels of atmospheric pressure, very high temperatures, and sulfuric acid

The surface of Mercury is very rocky, and has many pits and craters on it due to the large number of meteors that have collided with the surface over the years. According to all all observations that muggle spacecraft has made, the surface of Mercury is dead, with no signs of life or liquid water. This is largely due to its lack of atmosphere and extreme temperatures. Also due to the lack of atmosphere, Mercury has no weather or wind, and the surface has few distinguishing features such as riverbeds or dust storms. Much of the surface is similar to the surface of Earth's moon. Beneath the surface of mercury is a solid core, which is very rich in iron deposits. The core is large compared to the total size of the planet, the largest ratio of any planet or dwarf planet in our solar system.

However, it turns out that Mars is much more hospitable to life on its surface than Venus. Due to its runaway greenhouse effect, our sister planet is the hottest planet in our solar system. Temperatures on the Venusian surface can reach smoldering temperatures of nearly 900 degrees Fahrenheit, hot

Mercury's surface is heavily cratered. There are two distinct types of craters that can be observed on Mercury's surface; the more common impact crater - formed during asteroid impact, and pit craters - formed from the collapse of subterranean magma chambers. The former, impact craters, are typically more circular in shape and are accompanied by high ridges around the perimeter of the impact where debris from the impact was ejected. The latter, pit craters, are more irregular in shape and do not have the perimeter ridges. On the smoother plains of the surface compression folds can be seen, these are thought to be caused by the cooling of Mercury's core causing the surface to contract. The surface of Mercury consists of dark porous rock and because

After the sun sets, the planet Mercury is out. The telescope rocks back and forth from the wind, but a small charm is cast and it stabilizes. The brightness of the moon is distracting to the plain eye, but this telescope was enchanted to focus. With the light dying and the wind whipping around the Astronomy Tower, you'd think it would be hard to see the details of Mercury, but the planet was in perfect view. The surface of the planet looked like a burn victims skin, craters upon craters devoured the graying celestial object. Boulders covered the area that was smooth and the bottom of the pits. Mercury's craters had formed in paths that looked almost like rivers flowing on the surface, which, upon closer inspection, proved to be almost accurate.

Mercury's surface geology is similar in appearance to that of the Moon, showing extensive plains and heavy cratering, indicating that it has been geologically inactive for billions of years. Mercury was heavily bombarded by comets and asteroids during and shortly following its formation 4.6 billion years ago, separate subsequent episode. During this period of intense crater formation, the planet received impacts over its entire surface. During this time the planet was also volcanically active, leading to more interesting geological impacts. Craters on Mercury range in diameter from small cavities to huge impact basins and range in all states of degradation. There are two distinct plains that are present on Mercury. These inter-crater plains appear to have superseded many of the early craters, and signs of these early craters are still visible to sight.

I force my fingers, numb from the cold, to work, as I finish assembling Professor Polgara’s new Scope 72, a fantastic black and golden telescope. She lent it to me with the promise of it being returned in absolute perfect condition, and accompanied by a report on my observations. My assignment for this morning: the elusive planet Mercury.

Planet surface conditions: Mercury’s surface is similar to our moons. Its surface is littered with deep craters. 3.8 billion years ago was overwhelmed by a huge amount of craters and was believed that the surface was volcanically active.

The surface of Mercury is heavily cratered and closely resembles the surface of the Moon. The largest crater on Mercury’s surface is called Caloris Basin and it was created by one of the largest impacts in the history of Solar System. There is also present a number of craters that have irregular shape and slightly different color from the rest of the surface that could be an evidence of past subsurface volcanic activity. Probably the most unusual feature of Mercury are compression folds that were most likely caused by the contraction of the surface during the cooling of the planet. However some of those folds seem to be younger and are probably caused by tidal forces of the Sun. Mercury’s poles seem to be brighter than the rest of the planet which may be an indicator of the presence of the polar ice caps.

It was a clear but frigid December morning when I decided to complete my observations of the planet Mercury. I knew I would have to get up very early if I was to catch the sunrise, and with it one of the moments of the day at which Mercury is most clearly visible. I had brought with me the magical telescope lent to me by Professor Turing. This telescope could zoom in much farther than even the lab-grade Muggle telescopes. With this magical telescope, on such a cloudless day, I would be able to make detailed observations of Mercury.

The planet is likewise a slow rotator, with a 243-day long Venusian day and a circle around the sun at 225 days. Its environment is thick and contains Carbon Dioxide (CO2) and Nitrogen (N). In addition, Venus has no rings or moons.

Although there is no life, Venus has a plethora of mountains, continents, and craters. The craters imply that the surface of Venus is between three hundred and five hundred million years old. Impact craters have several classifications. To determine the impact origin for a crater, scientists look for a circular rim outlife,

The planet Mercury looks a little bit like Earth's moon. Mercury’s surface is covered with craters caused by asteroids impacts similar to the ones on the Moon. It also has basins and several wrinkles called lobate scarps. It has a light grey outer layer colour with several craters. It looks dry and I think that there is no possibility to sustain life. Fortunately, I got a chance to witness a large boulder of asteroid crashing towards the surface of Mercury. It
