The surface of Mercury
The most notable thing about the surface of Mercury are the many craters. Since the planet has a very thin atmosphere, clashes with comets and asteroids caused a lot of damage. Some craters are formed billion years ago, others are younger. These craters can be very deep, and their size ranges from a single meters to multiple kilometres. The Caloris Basin, the largest crater of Mercury, has a diameter of no less than 1,500 kilometres. A terrain of hills and mountains on the other side of the planet is believed to be caused by a shock wave generated by the impact the creation of the Caloris Basin had. Another feature of the planet are the “ghost craters”. These are former craters that are filled with volcanic material from volcanos that exploded a few billion years ago. The outline is still marked by ridges that form circles. One can also find highlands, mountains, plains and valleys on Mercury.
The climate on Venus

The average surface temperature is 500 degrees Celsius. An important reason for this high temperature are the clouds on the planet. From a distance they look similar to the clouds on Earth, but instead of water the clouds on Venus are made up of carbon dioxide. By absorbing infra-red light this greenhouse gas keeps the planet hot. Since Venus is also tilted with 23,4 degrees (Earth only with 2,7 degrees), seasons don’t exist at Venus. Everywhere at every time of the year the planet has almost the same high temperature. It is believed that Venus once had a climate like Earth, but it is still unknown how and why the greenhouse effect took
Mercury, the closest planet to the Sun, is a rocky planet. The heavily cratered planet suggests that meteors or comets were frequent many, many years ago. Mercury's boulder littered surface and pale gray appearance slightly resembles Earth's moon. Like Mars, Mercury is covered in pulverized dust. What Mercury lacks in this, is weather. Muggle probes bring images to us that show no signs of wind, dust storms, or clouds. No rivers have been found on Mercury. Lack of clouds and rivers, (and oceans) suggests that there is no water on the closest planet to the Sun, Mercury. One of Mercury's most famous craters is Caloris basin, which is 1550 km in diameter. Another of Mercury's most famous craters is called Rachmaninoff. Rachmaninoff is 306 km in diameter. These two very large craters were created by astroids impacting the planet in Mercury's early history.
For my vacation, my family has chosen to go to Venus. This our first year traveling outside of earth so we chose a planet close. Venus is covered with a thick layer of sulfuric acid which will be a blast to land into but on the inside Venus is solid. Venus shines super bright and has orangish yellow tint. The overall look of Venus is dreary and the gas covers the area with a goldish hue and everything looks like gunmetal. Venus is VERY hot, it temperature reaches to about 870 degrees Fahrenheit! On top of the scorching heat the Atmospheric pressure is bone crushing and highly dense.Venus is about 0.72 light years away from the Sun and blank light years from Earth. Venus is very much like earth and not very much like earth. Venus is about the same size as earth
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 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
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.
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.
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.
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.
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 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.
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
Scientists examined the Venusian atmosphere and found out that above the clouds the temperature is about 13oC, in contrast, at the surface of Venus the temperature gets as high as 465oC. It is believed that the principle cause of the extreme surface temperature is the consequence abundant carbon dioxide (CO2) in the atmosphere. Scientists concluded that Venusian atmosphere undergoes greenhouse effect. In essence, the heat delivered from the Sun enter the atmosphere and is radiated out, then again, it does not leave the atmosphere due to its heavy clouds that impede it from such. For this reason, Venus’ surface temperature is higher than that on Mercury – higher than any other planet! – leaving no chance of life.
