Mercury - The first fact that makes Mercury a unique planets is that Mercury has no moons or rings because of its low gravity and lack of atmosphere there is only one other planet in the hole solar system that has no moons. Second, Mercury is only the second hottest planet because Mercury has no atmosphere to keep heat in at night, thus it has the most extreme temperatures of all. Lastly, Mercury only turns very slowly on its axis, taking 59 days to complete the turn from day to night
Venus- First, Venus is the hottest world in the solar system, its dense atmosphere traps heat in a runaway version of the greenhouse effect that warms Earth. Second, the surface of Venus is extremely dry. During its evolution, rays from the sun evaporated water

It is not thick enough to trap the sun's heat so the planet is very cold, also Mars has very weak gravity which cannot hold onto the atmosphere well. Second, the rust layer is very thin and Mars has such large storms that they sometimes cover the entire planet. Underneath the layer is a volcanic rock that is very similar to earths. Mars also has some of the largest dust storms in the galaxy, whipping red dust into the light atmosphere around the planet. The southern hemisphere of Mars is predominantly ancient cratered highlands somewhat similar to the Moon. In contrast, most of the northern hemisphere consists of …show more content…
The rings are made almost entirely of water ice, with a trace component of rocky material. Second, Saturn’s atmosphere is composed of roughly 96% hydrogen and 4% helium, with trace amounts of ammonia, acetylene, ethane, phosphine and methane. Second, Like Jupiter, Saturn is about 75% hydrogen and 25% helium with traces of water, methane, ammonia and rock, similar to the composition of the primordial Solar Nebula from which the solar system was formed. Lastly Saturn is another gas giant, Saturn has a small rocky core covered with liquid
My research paper will investigate the Greek God Apollo. The reason I chose Apollo was I have never had a chance to look into other Gods or Goddess’ other than Zeus, Poseidon, and Hades. The next seven paragraphs are paraphrased depictions, stories and relational information directly related to the god Apollo The information was compiled by author: Atsma, Aaron J., on the website: Theoi.com.

The majority of mercury sett;es into the surface sediment where the amount of mercury was2.5 times more than the deep sediment. This of course leads to an even greater chance of the mercury getting recycled into the food chain rather than decomposing.
Saturn is the sixth planet in the galaxy but is not in fact the only planet with rings. Saturn is also the second largest planet after jupiter. It is also known as a gas giant due to the fact that it is predominately made up of hydrogen and helium which are numbers 1 and 2 on the periodic table. It is also the only planet in the solar system that is less dense than water. Saturn is so big that it and Jupiter make up 92% of the planetary mass in our solar system according to Jonathan J.Nettelmann who wrote Space Science Reviews on May 10 2010 so it is pretty recent.
Volcanoes- the ash emitted during the eruptions cool the global temperature, in their absence the temperature has been on the rise.
This planet is about half the size of Earth, and the second smallest planet in our Solar system. Mars is usually known as the “Red Planet” because of its red color, which is due to the concentration of iron oxide and dust and rock covering its surface, yet it’s the main component is Carbon Dioxide. Mars has a very thin atmosphere, which leads to a wide range in temperatures because it cannot trap solar heat. Hence, Mars’ temperature is a lot colder than that of Earth’s, at about minus 80° Fahrenheit. Mars is home to the highest mountains and volcanoes in the Solar System, such as Olympus Mons (biggest volcano) and Valles Marineris (one of the largest canyons). Mars experiences seasons just like Earth, except that they are twice as long as that of Earth’s. The explanation for these giant mountains is Mars weak surface gravity. Mars has two known moons, Phobos, and Deimos. Mars is currently a very important target for NASA and other space exploration because it is the planet most prone to life, after Earth.
Firstly, Venus’s atmosphere is heavily laden with carbon dioxide (CO2), which makes up 96 percent of its atmosphere, 3.5 percent is made of nitrogen, and the remaining 0.5 percent is a combination of water vapor, sulfuric acid (which produce Venus’s thick, stable clouds), hydrochloric acid, and hydrofluoric acid. Venus’s upper atmosphere is cool, which the lower atmosphere is extremely hot and causes the surface temperature to rise to 470C (880F). Venus’ present atmosphere is very dry, but shows signs that it may have once contained water. An abundance of deuterium—the heavy isotope of hydrogen—developed, but was broken down into hydrogen and oxygen atoms by ultraviolet radiation that could not be absorbed by Venus’s lack of an ozone layer (Seeds).
The main reason for Uranus and Neptune are bluer than Jupiter and Saturn comes down to layers of the planets atmospheres. Uranus and Neptune have almost only methane clouds with an occasional ammonia cloud floating around with it. Jupiter and Saturn, however, have many different gas clouds floating around in it including clouds of water, ammonia and ammonium hydrosulfide. All of these different clouds are only able to form where the temperature is right for them. This is why the methane gas planets are farther away then the water and mainly ammonia ones. Now when it comes to how the planets might have formed could be just due to distances and atmosphere. The farther the planet is from the sun the colder it is. The ultra violet rays heat up
Neptune gets its name from the Roman god of the sea. Neptune is the eighth planet from the sun and is the fourth largest. Neptune was discovered after scientist noticed that Uranus orbit didn't follow Newton's law, it was presumed that there must be another planet. Galileo originally thought Neptune was a star. Pluto's orbit is so eccentric, it sometimes crosses the orbit of Neptune making Neptune the most distant planet from the Sun. Neptune has been visited by only one spacecraft, Voyager 2 on Aug 25, 1989. Much of we know about Neptune comes from this single encounter. Neptune's blue color is largely the result of absorption of red light by methane in the atmosphere. Neptune has rapid winds and large storms. Neptune's winds are the fastest
Mercury is a very gray planet, which houses no living creatures or any ‘life’ in General. Mercury's surface is covered in impact craters, basaltic rock and smooth plains, many of them caused by what they believe is flood volcanism. Other features include vents which seem to be the cause of magma-carved valleys, often-grouped irregular-shaped, termed "hollows" that are believed to be the cause of collapsed magma chambers throughout the planet. The biggest crater on mercury was named Caloris Basin, and it has a diameter of 1550 km. Overall, about 15 impact basins have been identified on the part of Mercury that they were able to get a clear picture of. Some impact craters on Mercury are not very round, irregular shaped depressions or pits, and these are called ‘pit- floor’ craters.
The gas giants are a collection of planets in our solar system. As can be told from their name, they are mostly composed of differing mixtures of gases and ices. The gas and ice composition in question varies among the different planets. This mix of gases gives much of the planets an extremely thick atmosphere. At the very center of a gas giant is a core of liquid heavy metals. The gas giants are also called Jovian planets, taken from the largest planet in our solar system: Jupiter. Due to the fact the the majority of a gas giant planet is gas, the planet isn’t very dense and therefore, very large as a result. In fact, all of the gas giants are vastly larger than all of the terrestrial planets. Another common factor of the gas giants are their large amount of moons. The terrestrial planet, Mars, has the largest amount of moons, 2. The amount of moons of Mars is dwarfed in comparison to Saturn’s and Jupiter’s moo...
Known as “Earth’s twin”, Venus is very similar to Earth in composition, size, mass, and gravity. However, their temperatures are not so similar. The average temperature on Venus is a toasty 460 degrees Celsius (864 degrees Fahrenheit), as opposed to the cool 14 degrees Celsius (58.3 degrees Fahrenheit) Earth experiences. Needless to say, it would not be an ideal vacation spot. Venus is the hottest planet in the solar system, thanks to the runaway greenhouse effect. The atmosphere of Venus is also majorly different from Earth. It is composed of 97% carbon dioxide and 3% sulfuric acid, with an atmospheric pressure that is ninety-two times that of Earth. This pressure would be the same as being in the lowest depths of the ocean on Earth. However, like Earth, Venus is one of the four terrestrial planets, meaning it has a rocky surface, and a surface area of 177.7 million square miles. The gravity, which is 8.87 meters per second is very similar to Earth. Its mass is also very similar, 4.867E24 kilograms, and a density of 5.20 grams per centimeter.
First, If Saturn were to be put in water, it would be able to float. Saturn is mostly made up of gas which is lighter than water hence, it can float. Second, There is no changing of seasons on Venus. This is due to the axial tilt causing there to be almost no difference between the seasons. Lastly, The sun is so strong, if you were to stand 145 kilometers away from it, you could burn in a matter of seconds. This shows how strong the sun really is. I just find the facts about the night sky so
Mercury is the first planet closest to the Sun. It is the smallest planet in the solar system. Mercury rotates three times in two of its years. One of Mercury's days is equal to 176 Earth days because its rotation is very slow. What is weird is that its day is longer than its year. Mercury’s year is about 88 earth days the shortest in the solar system. It has the shortest year because it is closest to the Sun.
The fourth planet from the sun is Mars. “Mars is named after a mythological figure-the Roman God of War. Due to Mars color it is also known as the red planet. Mercury is the tiniest planet then Mars. Scientist have found that mars has the largest mountain compared to the other planets. Furthermore, this mountain is named Olympus Mons, it is a shield volcano, it is 21 km high and 600 km in diameter. Scientist have discovered recent lava on the planet, therefore the volcano may still be active.
We know most about the crust of the Earth which is the outermost sphere. This layer is very thin compared with the diameter of the whole Earth. It is only about 10 km thick under the ocean and about 30 km thick on land. It consists of rock which contains a lot of minerals. These are usually in compounds called oxides, containing oxygen, or sulfides, containing sulfur.
